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!
