%X In this paper we consider constraints, as a new research area for cooperating distributed (CD) grammar systems. Constraints are based on the notion of a trajectory. The flexible approach provides a framework to study some interesting properties of a CD grammar system like fairness or parallelization of languages. The use: of teams in the derivations of words is also considered.
