We did not measure the standard deviation and variance of the number of enumerations nor of the CPU time.
Moreover, our hybrid strategies are better (enumeration and time) than the pure first one, and close (better for enumerations, worse in time, but less than an order of magnitude) to the first- fail one.
Constraint propagation based solvers (CP) (Apt, 2003; Bessiere, 2006) are complete methods for solving Constraint Satisfaction Problems (CSP): they interleave enumeration and constraint propagation.
Enumeration creates one branch by instantiating a variable (e.
Numerous studies have been conducted about enumeration strategies (see e.
In our hybrid solver, we run a LS before enumeration.
We aim to obtain a solving process in which enumeration strategies (and more especially variable selection) impact less the solving efficiency: our goal is to reduce the effect that could have a bad strategy, either imposed by the system or selected by the user when this one does not know which strategy is the best adapted to his problem.
The technique consists in improving standard enumeration strategies.
the problem that remains after removing variables that have been instantiated in CP (either by enumeration or propagation) and removing constraints that are satisfied by these assignments.
