摘要
More than 30 years ago, Karp conjectured that all nontrivial monotone graph properties are evasive, i.e., have decision tree complexity ((n)(2)), where n is the number of vertices. It was proved in 1984 by Kahn, Saks, and Sturtevant [Combinatorica, 4 (1984), pp. 297-306] if n is a prime power by a topological approach. Using their method, we prove a lower bound of 1/3 n(2) - o(n(2)) for general n.
