WebHuffman Encoding: Greedy Analysis Claim. Huffman code for S achieves the minimum ABL of any prefix code. Pf. (by induction) Base: For n=2 there is no shorter code than root and two leaves. Hypothesis: Suppose Huffman tree T’ for S’ of size n-1 with ω instead of y and z is optimal.

WebHuffman’s coding gives an optimal cost prefix-tree tree. Proof. The proof is by induction on n, the number of symbols. The base case n = 2 is trivial since there’s only one full binary tree with 2 leaves.
