This is a visual explanation and exploration of adaptive Huffman coding and how it compares to traditional static Huffman coding. Specifically, we will focus on how our encoding trees might differ when using adaptive vs. static Huffman.
First, we will explore how traditional Huffman coding builds its encoding tree for a specific string, in this case "bookkeeper". We will then do the same for adaptive Huffman coding using the FGK algorithm and compare these two trees. At the end, you can further explore how static vs. Huffman coding trees compare through other strings.

Before we get started, let's quickly discuss what exactly Huffman coding is. When we transmit information, we generally need to convert some sort of data (text, pictures, etc.) into binary. To do this, we assign codes to help us distinguish between different pieces of data.
For example, if we had the string "abca", we might assign codes like: $a$ = 00, $b$ = 01, $c$ = 10. This would make it so that our binary encoding of "abca" is "00 01 10 00".
But what if we wanted to encode "aabaacaa"? If we used our original encoding where we use two bits for each character, we would be treating $a$ and $c$ with equal importance, even though $a$ appears much more.
Wouldn't it be more efficient if we used fewer bits for $a$ and more bits for $c$? This is where Huffman coding comes in.
Huffman coding is a lossless data compression algorithm that assigns variable-length codes based on the frequencies of our input characters.
In order to determine what code to assign to each character, we will first build a binary tree that will organize our characters based on frequency.
As an example, let's encode the string "bookkeeper". Before we can start encoding, we will build our Huffman tree for this string, which will in turn show us what binary encoding we will use for each character.
To start, we need to count the frequency for each character in our string and store these frequencies in a table.
We will use this table to add nodes and edges that will build up our tree.
First, we start by adding leaf nodes for the two characters that occur the least. In this case, we have a tie between $b$, $p$, and $r$, so we'll just arbitrarily choose $p$ and $r$.
When we add in our leaves for $p$ and $r$, we will attach them to a parent node for a new pseudo-character "pr". This pseudo-character represents occurrences of $p$ or $r$ so it's frequency is equal to the frequency of $p$ plus the frequency of $r$.
We will also update our table to include our new pseudo-character. We can get this by simply merging the columns of $p$ and $r$.
With a now reduced table, we can repeat this process again for our updated values.
As we can see, $b$ has the lowest frequency in our table so we'll use that. For the second lowest frequency, there is a tie between $k$, $o$, and "pr", so we can again pick arbitrarily. Let's use our pseudo-character "pr".
Since we don't have a leaf node for $b$ yet, we will have to add that into our tree.
Then, as we did before, we'll attach our $b$ node and our "pr" node to a parent node for a new pseudo-character "bpr".
Finally, we'll update our table to reflect our new pseudo-character.
It looks like our tree is coming along, but it doesn't quite have everything yet.
To keep going, we can repeat this process again...
...and again
...and again
...until our table is only left with one value, a pseudo-character containing all of our original characters. This means we're done building our Huffman tree!
So how do we use this tree to assign codes?
As we walk from root to leaf, we will denote a left traversal with "0" and a right traversal with a "1".
In our walk from root to the $p$ leaf, we go left, right, right, and left again. This means we will use four bits to encode $p$ as "0110".
For our walk to $k$, we traverse right then left. This means we will only use two bits to encode $k$ as "10".
It seems like our tree works - hooray for efficiency!
If we do this for all of our characters, we get our full binary encoding scheme. Let's compare this new Huffman scheme against a naive encoding scheme where we just arbitrarily assign binary codes.
| char | $b$ | $e$ | $k$ | $o$ | $p$ | $r$ |
|---|---|---|---|---|---|---|
| freq | 1 | 3 | 2 | 2 | 1 | 1 |
| old code | 000 | 001 | 010 | 011 | 100 | 101 |
| new code | 010 | 11 | 10 | 11 | 0110 | 0111 |
Using the naive scheme, encoding "bookkeeper" would take 30 bits. Using our Huffman scheme, we only use 25 bits to encode, which is a roughly a 17% improvement!
A small thing to note: as we were building our tree, when choosing our two least frequent characters in our table, we repeatedly had ties between three or more characters. When this happened, we would choose two of our tied elements arbitrarily.
By doing this, we can see that our arbitrary choice will change our tree. This means we can actually get multiple different trees from the same input string. For example, we could have initially chosen to start with $b$ and $r$ instead of $p$ and $r$. If we had done this, we would get a very similar tree but the $b$ and $p$ nodes would have been swapped.
While these trees might differ in their arrangement and shape, they are all valid Huffman trees. Since the algorithm is based on frequencies, this means that it doesn't matter if we assign a three-bit code to $b$ and a four-bit code to $p$ or vice versa. The tree and resulting encoding scheme will still result in the same efficiency improvement.
So how does this tree and this encoding compare to the one produced using adaptive Huffman coding? Keep scrolling to find out!

How to Fix Crashes in The Testament of Sherlock Holmes The Testament of Sherlock Holmes is often cited as one of the best entries in Frogwares’ long-running series, but for modern PC players, it can be a technical headache. From crashing on startup to freezing during cutscenes, the game’s 2012 engine often struggles with Windows 10 and 11.
If your investigation is being cut short by technical bugs, here is a comprehensive guide to getting the game stable. 1. Disable the Steam Overlay
A common culprit for crashes in older titles is the Steam Overlay. The game’s engine sometimes conflicts with the UI layer Steam tries to inject. Open your Steam Library. Right-click on The Testament of Sherlock Holmes. Select Properties.
Under the General tab, toggle off Enable the Steam Overlay while in-game. 2. Force Compatibility Mode and Admin Privileges
The game was designed for Windows 7. Modern permission settings can sometimes prevent the game from accessing necessary files, leading to immediate crashes.
Go to the game’s installation folder (usually Steam\steamapps\common\The Testament of Sherlock Holmes).
Find the main executable (usually game.exe or Sherlock.exe). Right-click it and select Properties. Navigate to the Compatibility tab.
Check Run this program in compatibility mode for: and select Windows 7. Check the box for Run this program as an administrator. Hit Apply and OK. 3. Install Legacy PhysX Drivers
The game utilizes Nvidia PhysX for its physics engine. Modern Nvidia drivers often lack the legacy files required by older games. Even if you have a top-tier modern GPU, the game might crash because it can’t find the specific version of PhysX it needs.
Download and install the NVIDIA PhysX System Software Legacy Driver directly from the official Nvidia website. Restart your computer after installation. 4. Adjust the Resolution and Refresh Rate
The Testament of Sherlock Holmes is notorious for crashing if it attempts to run at a refresh rate your monitor doesn’t support or at an ultra-wide resolution the engine can't handle.
Try lowering your monitor's refresh rate to 60Hz via Windows Display Settings before launching.
If you can reach the main menu, set the game to Windowed Mode or Borderless Window to see if stability improves. 5. The "White Screen" Startup Fix
If you get a white screen and a crash before the menu even loads, it is usually a codec or intro video issue. Navigate to the game folder. Find the folder named videos.
Rename the intro video files (like Logo_Frogwares.bik) to something else (e.g., Logo_Frogwares.bik.old).
The game will skip these files and go straight to the menu, often bypassing the crash point. 6. Verify Game Files
If all else fails, a file may have been corrupted during download.
In Steam, right-click the game > Properties > Installed Files. Click Verify integrity of game files.
By following these steps, you should be back to roaming the streets of London in no time. Most players find that the PhysX Legacy Driver and Compatibility Mode solve 90% of all crashing issues.

Sherlock.exe (or the game’s main executable) → Properties → Compatibility tab.Windows 7.Application.The rain had been a steady, unforgiving drum for two days. London’s lamps threw molten halos into the gutters, and the river moaned under a skin of oil-slick reflection. In a narrow, dim room on the third floor of a nondescript Baker Street building, an old oak desk bore witness to trembling hands and a single, stubborn lamp. A scrap of paper lay at the center of the desk like a broken promise: "The Testament of Sherlock Holmes — Crash Fix."
Inspector Lestrade, who usually preferred the blunt instruments of constables and warrants, stood awkwardly in the doorway, hat in hand.
"You asked for my company," he said, trying to sound casual and failing.
The writer—Miss Eleanor Myles, a young cryptanalyst from Scotland Yard’s experimental bureau—smiled without warmth. "You were the nearest person I could find who still believed in the impossible."
Lestrade’s eyes drifted to the manuscript beside the scrap. It was battered, dog-eared, its spine reinforced with tape, and its title repeated in a careful, uncertain script. Eleanor took a breath and began.
"It arrived three nights ago," she said. "A message, encoded in a cipher we had been unable to break. When I finally opened it, this manuscript unspooled. It claimed to be from Sherlock Holmes."
Lestrade's laugh was the sound of coal and disbelief. "Holmes? Dead these ten years, Mrs. Hudson still insists—"
"Not dead," Eleanor interjected. "Hidden. He calls it a 'testament' because it is both confession and instruction. He writes of a flaw in a system—not a mechanical clock, but a network, interwoven into the fabric of communications across Europe. He calls it a 'crash'—not a carriage, but a cascade: one node fails, and all that depends on it plummets."
Lestrade blinked. "Some kind of conspiracy?"
"Less conspiracy than design," Eleanor said. "Holmes describes an apparatus—strings of telegraph relays, pneumatic vaults of data, and the human operators who are the weak links. He sketches diagrams of routing decisions, of priorities and fail-safes, and then he marks a single error—the Crash. He calls for a 'fix' that is as much moral as technical."
Lestrade grunted. "And you believe him."
"You believe?" Eleanor shot back. "You find me a cipher that spells his hand, the precise cadence that only Watson once could parody, and tell me not to. Besides," she added, softer, "the manuscript knows things only Holmes could know. It names a man—Eustace Kynwell—who died in an accident and yet left a letter addressed to no one. It knows where the letter was hidden."
Against his better judgment, Lestrade went with her. They followed Holmes' footnotes across London: a tobacconist in Seven Dials who kept ledgers in Greek, a night-club pianist who hummed in Morse, a watchmaker whose clocks all ticked thirteen times a minute. Each discovery validated the manuscript. Each clue unraveled a skein of connection that led, inevitably, to the seam where technology and human trust stitched together.
At a warehouse on the Thames, behind barrels and old telegraph equipment, they found a machine—an angular, brass-frame contraption that hummed with latent power. It was not merely a messenger of messages; it was a decision-maker. Its relays could prioritize one message over another, delay or accelerate, and thus tilt fate by seconds and cents. Holmes, in the testament, called it the Arbiter.
The Arbiter had been designed to prevent wartime panic by regulating communications: insure continuity, ration bandwidth, and prevent floods of rumor. But as Holmes wrote, a test of logic had revealed a paradox. The device, when faced with two contradictions both claiming priority, would split its logic and freeze—an infinite recursion that caused a crash: wires burnt, operators fainted, trains halted, lives endangered. Holmes' fix was not a new gear or a code patch—it was a testament of values.
"He writes," Eleanor read aloud, "that machines obey rules; men obey motives. To mend the Arbiter, man must be reintroduced to the machine: the operator must decide, with judgment, which message carries truth and which carries panic. The remedy is a human veto—small enough to prevent misuse, large enough to stop a cascade."
Lestrade frowned. "An honest man at every switch? Who chooses these men?"
"Holmes foresaw that," Eleanor said. "He left tests—riddles, moral dilemmas, puzzles in human behavior that reveal honesty more surely than letters of recommendation. He calls them the Ordeal: a short, merciless appraisal that measures not intellect but temperament."
They set out to implement it. The Yard and the telegraph companies bristled with bureaucracy, but Holmes' lucidity and Eleanor's evidence won the reluctant consent of a few directors. Operators were tested not on mathematics but on choices: whether they would privilege a child's plea over a dignitary's demand, whether they would delay a rumor to verify a name. The Ordeal did not produce saints; it produced men and women who could bear a tether of responsibility.
On the day the Arbiter was restarted, a small crowd gathered—engineers with grease on their sleeves, clerks with pigeonholes of messages, and officials who had learned the cost of traffic stopped. Holmes' instructions—careful, exacting, and uncompromising—were read aloud. Eleanor's hand trembled only when she lifted the final page where Holmes had written what looked suspiciously like a farewell.
"I have seen," the manuscript said, "the neat arithmetic of machines and the messy arithmetic of souls. I prefer the latter. When wires fail, when ciphers yield, remember that the smallest truth is the one you are willing to act upon at cost."
The Arbiter hummed. A test message that should have produced conflicting priorities was sent: a code designed to trip the machine's deadlock. The brass teeth ticked, the relays stuttered—and then waited. A human hand—calloused, steady—pressed a lever. The machine accepted that choice and routed the messages alternately, preserving both urgency and truth. The crash had not occurred.
Applause was not Holmes’ reward. Instead, a single visitor arrived before dawn the next morning at Eleanor’s office: a gaunt man with hawk-bones and a scarf over his mouth. He moved like a shadow that had learned to calculate angles.
"You have fixed a machine with a lesson in morals," he said. His voice held no surprise. "Your work amends a design and perhaps an error in judgment, Miss Myles."
Eleanor's mouth went dry. "Do you doubt it?" How to Fix Crashes in The Testament of
He smiled once—a brittle, quick thing. "No. I only note that the manuscript did not come without cost. The Arbiter’s survival required a disclosure. Holmes promised an ending: if the fix was enacted, he would relinquish his disguise and return the last of his papers to the world. If not..." The man shrugged.
Lestrade raised a hand. "You knew him, didn't you? This voice—?"
"I knew many voices." The man set a card on the desk. It read: "Aldridge Cole. Consultant."
"You are—"
"A chronicler," Aldridge said. "And the final courier."
Eleanor flipped to the last page of the manuscript. A sentence she had not noticed before stared up: "If this reaches the hands of men who choose the rightness of small things over the convenience of cold logic, let the name of the Arbiter be buried and its worship be of judgment, not efficiency. If they fail, burn these pages."
She looked at Lestrade, then at Aldridge. "And if we choose wrongly?"
Aldridge's eyes were flat. "Then the crash will be the least of our concerns."
They had chosen. The Arbiter would remain, but leashed: a human veto at every crucial node, a small ritual of accountability that transformed the machine from sovereign to servant. The telegraph companies grumbled, shareholders stormed, but the trains ran, messages were delivered, and the city breathed easier.
In private, Eleanor read the rest of the testament. It contained curious marginalia—half-phrases that fit no context, a baritone laugh in ink. Once, between diagrams, a line: "Remember Watson: the human heart is the last cipher."
She understood, at last, why the manuscript bore the name Crash Fix. Holmes had not merely fixed wires; he had repaired a habit—the inclination to defer judgment to circuits. He had, in his stubborn way, resurrected responsibility.
A week later, at dusk, a letter arrived, slipped under Eleanor's door. It was headed with a familiar flourish: S. H. No signature followed. Inside was a single line:
"You did what was necessary. Keep the test simple; teach it to those who will hold the levers."
Eleanor pressed the paper to her chest and laughed—a sound of exhaustion and relief. Lestrade, as they walked back into the rain, said nothing, only let the puddles shudder under their boots.
They never saw Holmes. They never confirmed if he had written the manuscript with his own hand or if it was the work of a careful mimic. It did not matter. The testament had done its work: it had reminded a city that some failures cannot be excused by complexity, and that the smallest human action—choosing to wait, to verify, to act at cost—can avert the collapse of the great things built upon us.
Years later, a boy at the telegraph office, sweaty-palmed and new to the Ordeal, would tell a visitor that the tests were old-fashioned, but they made the work honorable. "We learn more about being than about wires," he said.
The visitor smiled, slipped the boy a coin, and tucked the memory away like an old telegram—one that, even when unread, kept its weight.
And somewhere, under a different sky, a man with a scarf watched the city from a rooftop, as close to invisible as a comma. He folded his hands, unrolled a map, and wrote a note in the margin of an old page: "The machine is fixed. Mind the next fall."
The rain continued to fall. The city kept its rhythm, and people rose and fell, each in small, consequential ways. The testament had not ended the possibility of crashes, only made the cost of them harder to pay.
The Testament of Sherlock Holmes is notorious for stability issues on modern systems, particularly crashing during saves or at startup. The Whitechapel Memory Leak (Save Fix)
The most common crash occurs during manual or auto-saves, especially in high-detail areas like Whitechapel. This happens because the game, by default, is limited to 2GB of memory during the save process, which is often insufficient for modern hardware and high settings. The Solution: NTCore 4GB Patch to allow the executable to access more memory. Download the patch from the NTCore website Extract and run the patcher. Select the file in your installation directory.
Once you see "Executable successfully patched," the save-related crashes should cease. Startup & Compatibility Issues
If the game refuses to launch or crashes instantly, it often relates to outdated NVIDIA PhysX files or Windows compatibility quirks. PhysX Loader Fix: The game requires specific legacy PhysX files to run. Navigate to your NVIDIA folder (usually Program Files (x86)\NVIDIA Corporation\PhysX\Common
) and copy all files from there directly into the game's main installation folder where is located. Alternatively, download and install the NVIDIA PhysX Legacy System Software Compatibility Mode: Right-click Properties , go to the Compatibility
tab, and check "Run this program in compatibility mode for" and select Windows XP (Service Pack 3) . Also, check "Run this program as an administrator". Screen Scaling:
On Windows 10/11, if your display scaling is set to 125% or higher, the game may fail to open in full-screen. Set your Windows display scaling to before launching, or play in Windowed Mode General Maintenance The Testament of Sherlock Holmes - PCGamingWiki PCGW
The Testament of Sherlock Holmes (2012) often faces stability issues on modern systems like Windows 10 and 11, ranging from startup failures to "crash to desktop" (CTD) errors during saves. Core Fixes for Crashing
The 4GB Patch (Critical for Save Crashes): Frequent crashes, especially during auto-saves or manual saves in areas like Whitechapel, are often caused by memory limitations. Use the NTCore 4GB Patch on Game.exe to allow the game to use more virtual memory.
NVIDIA PhysX Files: If the game won't launch at all, it likely needs legacy PhysX files. Copy all DLL files from your local PhysX folder (typically C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common) directly into the game's installation folder where Game.exe is located.
Compatibility Settings: Right-click Game.exe, go to Properties > Compatibility, and set it to Windows 7 Compatibility Mode. Some users find that Windows 98/ME compatibility resolves stubborn save-related crashes, though it may impact performance.
Disable Splash Screens: Modifying the user.ini file (found in the game folder) to delete lines starting with splash_screen_start_... can bypass certain startup crashes. Common Technical Solutions
Screen Scaling: High DPI settings can prevent the game from opening. Set your Windows display scale to 100% (Settings > System > Display).
Windowed Mode: If full-screen crashes persist, force windowed mode by pressing Alt + Enter or unchecking "Fullscreen" in the options menu.
Verify Integrity: For Steam users, right-click the game in your library, select Properties > Local Files, and click Verify Integrity of Game Files to fix missing or corrupted data.
Refresh Rate: Systems running above 60Hz may experience instability; try lowering your monitor's refresh rate to 60Hz specifically for this title. Official Resources
Troubleshooting Guide: The Testament of Sherlock Holmes Crash Fixes Outdated game version : The game was released
Released in 2012, The Testament of Sherlock Holmes is widely considered one of the darker and more intricate entries in Frogwares’ long-running adventure series. However, even the world’s greatest detective can’t solve a mystery if the game won’t stop crashing to the desktop (CTD).
If you’re experiencing freezes, black screens, or sudden shutdowns, here is a comprehensive guide to getting the game running smoothly on modern hardware. 1. Verify Game Files (Steam/GOG)

Under the Compatibility tab, check Run this program in compatibility mode for: and select Windows 7. Check Run this program as an administrator. Check Disable fullscreen optimizations. 3. The PhysX Legacy Driver Fix
The Testament of Sherlock Holmes relies on NVIDIA PhysX. Even if you have a modern NVIDIA or AMD card, the game often looks for specific legacy files that aren't included in modern driver packages.
The Fix: Download and install the NVIDIA PhysX System Software Legacy Driver. This is a common requirement for games released between 2008 and 2013. 4. Limit Frame Rate and Disable V-Sync
Modern GPUs can push this game into hundreds of frames per second, which can cause the engine to overheat or crash during transitions.
NVIDIA/AMD Control Panel: Create a profile for the game and set a Max Frame Rate of 60 FPS.
In-Game: Try toggling V-Sync off if you experience crashes during cutscenes. 5. Visual C++ Redistributable Updates
The game requires specific C++ libraries. If these are outdated or missing, the game will fail to launch or crash during loading.
Ensure you have both the x86 and x64 versions of the Microsoft Visual C++ 2010 Redistributable installed. Many users find that reinstalling these specifically fixes "Startup Crashes." 6. Adjusting the Setup.ini (Advanced)
If the game crashes before the menu appears, it may be trying to launch at an unsupported resolution. Go to Documents\Games\The Testament of Sherlock Holmes. Open Setup.ini with Notepad.
Ensure the Width and Height match your monitor's native resolution.
Try changing FullScreen=1 to FullScreen=0 to force Windowed Mode, which is often more stable. 7. Audio Sample Rate
A rare but known issue involves high-end audio setups. If your audio is set to a sample rate higher than 48kHz, the game engine may struggle.
Go to Sound Settings > More sound settings > Right-click your output device > Properties > Advanced. Set the format to 24-bit, 48000 Hz (DVD Quality).
By following these steps, you should be able to step back into 1898 London without the frustration of constant technical hitches.
