  bibo_abstract:
  - 'In repeated interactions, players can use strategies that respond to the outcome
    of previous rounds. Much of the existing literature on direct reciprocity assumes
    that all competing individuals use the same strategy space. Here, we study both
    learning and evolutionary dynamics of players that differ in the strategy space
    they explore. We focus on the infinitely repeated donation game and compare three
    natural strategy spaces: memory-1 strategies, which consider the last moves of
    both players, reactive strategies, which respond to the last move of the co-player,
    and unconditional strategies. These three strategy spaces differ in the memory
    capacity that is needed. We compute the long term average payoff that is achieved
    in a pairwise learning process. We find that smaller strategy spaces can dominate
    larger ones. For weak selection, unconditional players dominate both reactive
    and memory-1 players. For intermediate selection, reactive players dominate memory-1
    players. Only for strong selection and low cost-to-benefit ratio, memory-1 players
    dominate the others. We observe that the supergame between strategy spaces can
    be a social dilemma: maximum payoff is achieved if both players explore a larger
    strategy space, but smaller strategy spaces dominate.@eng'
