One of the machine learning challenges posed by the robot soccer domain is to learn the opponents strategies. A team that may be able to do it efficiently may have the advantage to adapt its own strategy as a response to the opponent’s strategy. In this work, we propose a similarity function to compare two teams, and consequently their strategies, by the ability of one team to mimic the behavio...

Under some circumstances, a group of individuals may need to negotiate together as a negotiation team against another party. Unlike bilateral negotiation between two individuals, this type of negotiations entail to adopt an intra-team strategy for negotiation teams in order to make team decisions and accordingly negotiate with the opponent. It is crucial to be able to negotiate successfully wit...

We present a theory of rationality in dynamic games in which players, during the course of the game, may revise their beliefs about the opponents’ utility functions. The theory is based upon the following three principles: (1) the players’ initial beliefs about the opponents’ utilities should agree on some profile u of utility functions, (2) every player should believe, at each of his informati...

Opponent modeling is necessary in multi-agent settings where secondary agents with competing goals also adapt their strategies, yet it remains challenging because strategies interact with each other and change. Most previous work focuses on developing probabilistic models or parameterized strategies for specific applications. Inspired by the recent success of deep reinforcement learning, we pre...

Competitive fitness is the assessment of an individual’s fitness in the context of competition with other individuals in the evolutionary system. This commonly takes one of two forms: one-population competitive fitness, where competition is solely between individuals in the same population; and N-population competitive fitness, often termed competitive coevolution. In this paper we discuss comm...

27 JUlY 2017 | GEnEVa DNew WHO data from 28 countries representing approximately 70% of the global hepatitis burden indicate that efforts to eliminate hepatitis are gaining momentum. Published to coincide with World Hepatitis Day, the data reveal that nearly all 28 countries have established high-level national hepatitis elimination committees (with plans and targets in place) and more than hal...

It has been shown that people tend to view opponents as biased. Recent theoretical studies showed this tendency occurs due naïve realism. People be overconfident about their objectivity ? they believe see the world it really is (Naïve realism: Ross & Ward, 1995) hence, assume who have a different must biased (Pronin et al., 2004). This study examines effect of encountering clear demonstrations ...
