A preliminary taxonomy of multi-agent interactions
H. Van Dyke Parunak, Sven Brueckner, Mitch Fleischer, James Odell · 2003
Agent interactions are frequently characterized as "coherent," "collaborative," "cooperative," "competitive," or "coordinated." All of these are specializations of the more foundational category of "correlation," which can be measured by the joint information of a system. "Congruence" is an orthogonal category, reflecting the degree to which correlation and its specializations satisfy user requirements. Lack of correlation can sometimes arise purposefully, and requires the use of formal stochasticity.
