Which Dynamic Constraint Problems Can Be Solved By Ants?
There exist a number of algorithms that can solve dynamic constraint satisfaction/optimization problems (DynCSPs or DynCOPs). Because of the large variety in the characteristics o...

Solving subgraph isomorphism problems with constraint programming
The subgraph isomorphism problem consists in deciding if there exists a copy of a pattern graph in a target graph. We introduce in this paper a global constraint and an associated ...
