In the variant considered in this paper, questions with q many possible answers are allowed, further lies are constrained by a bipartite graph with edges weighted by 0, 1, 2.... (the \"channel\"). The channel Gamma is an arbitrary assignment stipulating the cost of the different possible lies, i.e., of each answer j not equal i when the correct answer is i by Gamma(i, j). It is also assumed that a maximum cost a (sum of the cost of all wrong answers) can be afforded by the responder during the whole game. We provide tight asymptotic bounds for the number of questions needed to solve this problem. The appropriate searching strategies are actually provided. We also show that adaptiveness can be dramatically reduced when the channel satisfies certain symmetry constraints. (C) 2007 Elsevier B.V.
