Abstract

A Boolean function f(x1,x2,...,xn) is elusive if every decision tree computing f must examine all n variables in the worst case. It is a long-standing conjecture that every nontrivial monotone weakly symmetric Boolean function is elusive. In this paper, we prove this conjecture for Boolean functions with twelve variables.
