Minimal Boolean Formulas
Read OriginalThis technical article details the discovery that 28 is the minimum number of AND or OR operators required to write any Boolean function of five variables. It describes the naive brute-force approach, the adaptation of the Floyd-Warshall algorithm to compute formula sizes, and the context of nearly being scooped by Knuth's work. The content is deeply rooted in computer science, algorithms, and Boolean logic.
