摘要

An extension of the WHILE-language is developed for programming game-theoretic mechanisms involving multiple agents. Examples of such mechanisms include auctions, voting procedures, and negotiation protocols. A structured operational semantics is provided in terms of extensive games of almost perfect information. Hoare-style partial correctness assertions are proposed to reason about the correctness of these mechanisms, where correctness is interpreted as the existence of a subgame-perfect equilibrium. Using an extensional approach to pre- and postconditions, we show that an extension of Hoare's original calculus is sound and complete for reasoning about subgame-perfect equilibria in game-theoretic mechanisms. We use the calculus to verify some simple mechanisms like the Dutch auction.
