Cooperative behavior is a subclass of collective behaviors.
Awareness of other members of the robot team is a necessary component of the cooperation, but it also accounts for an increase of the search space size. Cooperative robot learning must, in the first place, study the impact of robot awareness on the dimensionality of the search space. Practical bounds to the quality of the awareness come from the search space size increase associated with the addition of new members to the group. Experimental results agree with this assumption, which nevertheless depends on the robot's awareness field of view and, also, on the total number of neighbor robots.
