具有部分可观测预算的投标图对策

Bidding Graph Games with Partially-Observable Budgets

Guy Avni, Ismael Jecker, Djordje Zikelic

摘要:

两个玩家的零和“图形游戏”是一个中心模型,其过程如下。一个令牌被放置在图的一个顶点上,两个玩家移动它来产生一个无限的“游戏”,这决定了游戏的赢家或收益。传统上,玩家轮流移动代币。然而,在“出价游戏”中,玩家有预算,在每一轮中,拍卖(出价)决定哪个玩家移动代币。到目前为止,投标博弈仅被作为完全信息博弈来研究。在这项工作中,我们开始研究部分信息投标游戏:我们研究投标游戏中,玩家的初始预算是从一个已知的概率分布。我们表明,虽然对于某些投标机制和目标,它是直接适应的结果从全信息设置的部分信息设置,对于其他人,分析是更具挑战性的,需要新的技术,并产生有趣的结果。具体来说,我们研究游戏的“平均回报”的目标结合“穷人”投标。我们构建了一个部分知情的球员谁对一个完全知情的对手发挥最佳策略。我们发现,有点令人惊讶的是,在纯策略下的“价值”不一定存在于这样的游戏。

英文摘要:

Two-player zero-sum "graph games" are a central model, which proceeds as follows. A token is placed on a vertex of a graph, and the two players move it to produce an infinite "play", which determines the winner or payoff of the game. Traditionally, the players alternate turns in moving the token. In "bidding games", however, the players have budgets and in each turn, an auction (bidding) determines which player moves the token. So far, bidding games have only been studied as full-information games. In this work we initiate the study of partial-information bidding games: we study bidding games in which a player's initial budget is drawn from a known probability distribution. We show that while for some bidding mechanisms and objectives, it is straightforward to adapt the results from the full-information setting to the partial-information setting, for others, the analysis is significantly more challenging, requires new techniques, and gives rise to interesting results. Specifically, we study games with "mean-payoff" objectives in combination with "poorman" bidding. We construct optimal strategies for a partially-informed player who plays against a fully-informed adversary. We show that, somewhat surprisingly, the "value" under pure strategies does not necessarily exist in such games.
