The chapter discusses Huffman coding, a greedy algorithm used for optimal binary encoding based on frequency analysis. It explains how to construct a minimum cost encoding tree by recursively combining the lowest frequency characters until an optimal tree is achieved. The chapter also touches on the historical context of information theory and how Huffman's algorithm improved upon earlier methods.

A method of lossless data compression that uses variable-length codes for encoding characters based on their frequencies.
An algorithmic paradigm that builds a solution piece by piece, always choosing the next piece that offers the most immediate benefit.
The total frequency of occurrence of a set of characters, used to determine how to combine characters in Huffman coding.
A binary tree structure where the path length from the root to each leaf node (which represents a character) is minimized based on frequency.
