带预测的搜索博弈

Search Games with Predictions

Spyros Angelopoulos, Thomas Lidbetter, Konstantinos Panagiotou

AI总结:

本文研究搜索者拥有可能错误的隐藏者位置预测时的搜索博弈,首次完整刻画混合策略下一致性与鲁棒性的帕累托最优权衡,并给出适用于更广泛学习增强零和博弈的证明框架。

摘要:

我们引入对移动搜索者与静止隐藏者之间搜索博弈的研究,其新设定是搜索者拥有一些可能错误的信息,即关于隐藏者位置的预测。目标是建立搜索策略一致性(即假设预测正确时的最坏情况期望收益)与其鲁棒性(即对预测质量不作任何假设时的最坏情况期望收益)之间的紧权衡。我们的研究首次涉及混合(随机化)策略的全部能力;以往工作只关注确定性策略,或依赖随机性假设,而这些假设无法保证对抗情形下的最坏情况鲁棒性。我们为三个基本问题给出帕累托最优策略,即离散位置搜索、带随机遗漏的搜索以及无限直线上的搜索。作为贡献的一部分,我们提供了一个用于证明搜索博弈中最优权衡的新框架,该框架更广泛地适用于学习增强设定下的任何两人零和博弈。

英文摘要:

We introduce the study of search games between a mobile Searcher and an immobile Hider in a new setting in which the Searcher has some potentially erroneous information, i.e., a prediction on the Hider's position. The objective is to establish tight tradeoffs between the consistency of a search strategy (i.e., its worst case expected payoff assuming the prediction is correct) and its robustness (i.e., the worst case expected payoff with no assumptions on the quality of the prediction). Our study is the first to address the full power of mixed (randomized) strategies; previous work focused only on deterministic strategies, or relied on stochastic assumptions that do not guarantee worst-case robustness in adversarial situations. We give Pareto-optimal strategies for three fundamental problems, namely searching in discrete locations, searching with stochastic overlook, and searching in the infinite line. As part of our contribution, we provide a novel framework for proving optimal tradeoffs in search games which is applicable, more broadly, to any two-person zero-sum games in learning-augmented settings.
