Abstract

The prime implicate trie (pi -trie) of a logical formula is a tree whose branches are labeled with the prime implicates of the formula. The technology of reduced implicate tries is employed to analyze the structure of pi -tries. Appropriate lemmas and theorems are proved, and an algorithm that builds the pi -trie from a logical formula is developed. Preliminary experimental results are presented.
