### Huffman encoding: why is there no need for a separator?

You don't need a separator because Huffman codes are prefix-free codes (also, unhelpfully, known as "prefix codes"). This means that no codeword is a prefix of any other codeword. For example, the ...

### Huffman encoding: why is there no need for a separator?

It's helpful to imagine it as a tree. You are simply traversing the tree until you hit a leaf node, and then restarting from the root. From the algorithm which does huffman coding, you can see that ...

### Huffman Coding vs LZW Algorithm

In a gist LZW is about frequency of repetitions and Huffman is about frequency of single byte occurrence. Take the string 123123123. (The following is an oversimplification but will make the point) ...

### Maximum size of Huffman codes for an alphabet containing 256 letters

I don't see how to approach the problem. OK, here is how you can approach the problem. Can you solve this problem if you replace the number 256 with the number 3? How about 4? 5? Try solving ...

### How does a predictive coding aid in lossless compression?

Huffman coding, as usually applied, only considers the distribution of singletons. If $X$ is the distribution of a random singleton, then Huffman coding uses between $H(X)$ and $H(X)+1$ bits per ...

### Is huffman-encoding with distinct frequencies of symbols unique?

2 3 4 5 is a counterexample: 4 5 5 (combine 2 and 3 to make 5, and reorder) Now there are 2 choices for ...
