Uniqueness of Optimal Mod 3 Circuits for Parity
In this paper, we prove that the quadratic polynomials modulo 3 with the largest correlation with parity are unique up to permutation of variables and constant factors. As a conseq...

On the Huffman and Alphabetic Tree Problem with General Cost Functions
We study a wide generalization of two classical problems, the Huffman Tree and Alphabetic Tree Problem. We assume that the cost caused by the ith leaf is fi(di), where di is its d...
