Between the deterministic and non-deterministic query complexity
Abstract
We consider problems that can be solved by asking certain queries. The deterministic query complexity of a problem is the smallest number of queries needed to ask in order to find the solution with an input of size (in the worst case), while the non-deterministic query complexity is the smallest number of queries needed to ask, in case we know the solution, to prove that it is indeed the solution (in the worst case). Equivalently, is the largest number of queries needed to find the solution in case an Adversary is answering the queries, while is the largest number of queries needed to find the solution in case an Adversary chooses the input. We define a series of quantities between these two values, is the largest number of queries needed to find the solution in case an Adversary chooses the input, and answers the queries, but he can change the input at most times. We give bounds on for various problems .
