We analyze the evolution of behavioral rules for learning how to play a two-armed bandit. Individuals have no information about the underlying pay-off distributions and have limited memory about their own past experience. Instead they must rely on information obtained trough observing the...

We consider the situation in which individuals in a finite population must repeatedly choose an action yielding an uncertain payoff. Between choices, each individual may observe the performance of one other individual. We search for rules of behavior with limited memory that increase expected...

Individuals repeatedly face a multi-decision task with unknown payoff distributions. They have minimal memory and update their strategy by observing previous play (and not strategy) of someone else. We select behavior rules that increase average payoffs as often as possible in a large population...

The evolutionary basis for predicting the backwards induction solution in generic finite extensive-form games with perfect information is examined. Evolution is modelled using the replicator dynamic in combination with rare mutations that introduce a small change in the proportion of each...

We call a set of strategies "uniformly evolutionary stable" if the following holds after a small mutation of a monomorphic population playing a strategy in the set: a) No mutant strategy can spread. b) Mutant strategies not in the set will be driven out. c) The meaning of a "small mutation" can...

We extend the notions of evolutionary stability and, for the first time, that of neutral stability to asymmetric games played between two populations. Stability with respect to simultaneous entry of a small proportion of mutants into both populations is considered. Allocations where neither...

It is found that the “Theory of Moves” is adequate in a Cold War scenario, with functionally equal participants, such as the Cuban Missile Crisis. The destabilization of normal incentive systems, under power and information asymmetry, is what prevents an equilibrium from being reached, as...

Aim: To present a systematic development of the theory of combinatorial games from the ground up. Approach: Computational complexity. Combinatorial games are completely determined; the questions of interest are efficiencies of strategies. Methodology: Divide and conquer. Ascend from Nim to Chess...

The economic catch-up of the East Asian region went hand-in-hand with the emergence and even dominance of large quasi-state or private conglomerates. Such for example were the Zaibatsus in the pre-WWII and the Keiretsus of the post-WWII Japan and the Chaebols of South Korea which enjoyed...

Traditional game theoretic analysis proposes backward induction as a model of rational behaviour in games with perfect information. However, counterintuitive results have cast doubt on the predictive power of the theory. For example, in the Centipede Game, experimental evidence shows that...
