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...

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 model of social learning by Schlag (1996). Individuals must repeatedly choose an action in a multi-armed bandit. We assume that each indivdiual observes the outcomes of two other individuals' choices before her own next choice must be made -- the original model only allows for...
