Cooperation in Combinatorial Search

Combinatorics 2023-04-25 v1

Abstract

In the game theoretical approach of the basic problem in Combinatorial Search an adversary thinks of a defective element dd of an nn-element pool XX, and the questioner needs to find xx by asking questions of type is dQd\in Q? for certain subsets QQ of XX. We study cooperative versions of this problem, where there are multiple questioners, but not all of them learn the answer to the queries. We consider various models that differ in how it is decided who gets to ask the next query, who obtains the answer to the query, and who needs to know the defective element by the end of the process.
