Ant Colony Optimization and Constraint Programming
ISTE Ltd and John Wiley & Sons Inc (Verlag)
978-1-84821-130-8 (ISBN)
The second part describes the ant colony optimization metaheuristic and illustrates its capabilities on different constraint satisfaction problems.
The third part shows how the ant colony may be integrated within a constraint programming language, thus combining the expressive power of constraint programming languages, to describe problems in a declarative way, and the solving power of ant colony optimization to efficiently solve these problems.
Christine Solnon is Associate Professor at the University of Lyon 1 and a member of the LIRIS laboratory. She is Vice- President of the AFPC; the French association for constraint programming.
