Abstract

In this paper we consider a variant of the well-known Achlioptas process for graphs adapted to monotone Boolean functions. Fix a number of choices rNr\in \mathbb N and a sequence of increasing functions (fn)n1(f_n)_{n\ge 1} such that, for every n1n\ge 1, fn:{0,1}n{0,1}f_n:\{0,1\}^n\mapsto \{0,1\}. Given nn bits which are all initially equal to 0, at each step rr 0-bits are sampled uniformly at random and are proposed to an agent. Then, the agent selects one of the proposed bits and turns it from 0 to 1 with the goal to reach the preimage of 1 as quickly as possible. We nearly characterize the conditions under which an acceleration by a factor of r(1+o(1))r(1+o(1)) is possible, and underline the wide applicability of our results by giving examples from the fields of Boolean functions and graph theory.
