Direct Known Subclasses:

AbstractGlobalSearchSolver

public abstract class AbstractSolver
extends AbstractEntity

An abstract class handling the control for solving a problem

Field Summary

protected static java.util.logging.Logger	logger an object for logging trace statements
int	maxNbSolutionStored capacity of the history record (keeping solutions)
java.util.ArrayList	solutions The historical record of solutions that were found

Fields inherited from class choco.AbstractEntity

hook, problem

Constructor Summary

AbstractSolver()

Method Summary

boolean	existsSolution()
protected Solution	makeSolutionFromCurrentState()
void	recordSolution() recording the current state as a solution stores information from the current state in the next solution of the problem note: only instantiated variables are recorded in the Solution object either all variables or a user-defined subset of them are recorded this may erase a soolution that was previously stored in the ith position this may also increase the size of the pb.solutions vector.
void	restoreBestSolution()
abstract void	run() main entry point: running the search algorithm controlled the Solver object
void	showSolution() showing information about the last solution
protected void	storeSolution(Solution sol)
