CONTRAINTES: Constraint Programming

INRIA centre Paris-Rocquencourt building 8, France


"Le plaisir de comprendre comme seule contrainte."

The "Contraintes" group investigates the theoretical foundations, design, implementation and applications of rule-based modeling languages and constraint solving techniques in two main domains: combinatorial optimization and computational systems biology. More generally in the later domain, Contraintes develops formal methods for systems biology and investigates the tight integration of in silico and in vivo approaches using microfluidic and synthetic biology techniques.

Our activity reports are available from the official INRIA Web page of Contraintes.

Contraintes is associated to the PhD programs Sciences Mathématiques de Paris Centre and Frontiers in Life Sciences in Paris.

Contraintes is associated with Ron Weiss's Lab on synthetic biology at MIT, USA.
