abstract = "We introduce a cooperative co-evolutionary system to facilitate the development of teams of heterogeneous agents. We believe that $k$ different behavioral strategies for controlling the actions of a group of $k$ agents can combine to form a cooperation strategy which efficiently achieves global goals. We examine the on-line adaption of behavioral strategies using genetic programming. Specifically, we deal with the credit assignment problem of how to fairly split the fitness of a team to all of its participants. We present several crossover mechanisms in a genetic programming system to facilitate the evolution of more than one member in the team during each crossover operation. Our goal is to reduce the time needed to either evolve a good team or reach convergence.",
