Constructor Detail

HeuristicGeneticSolution

public HeuristicGeneticSolution(java.lang.String thisName)

Create a new instance of HeuristicGeneticSolution.

Parameters:

thisName - the solution name.

Method Detail

solve

public void solve(java.util.HashMap<java.lang.String,?> inputVariables)
           throws java.lang.Exception

Calculate the result of this solution over all problem datasets. The results are then put in a list and stored in the evaluation object.

Parameters:

inputVariables - an additional set of input variables or constraints. This can be null or empty.

Throws:

java.lang.Exception - any error.

solveNextSolution

protected EvalBounds solveNextSolution(org.ai_heuristic.eval.metric.MetricDataset problemDataset)
                                throws java.lang.Exception

Calculate the result of this solution over the specified problem dataset.

Parameters:

problemDataset - the problem dataset to evaluate.

Returns:

the entity solution, or null if the entity does not perform the solution. The solution evaluation includes an upper and lower bound on the possible values.

Throws:

java.lang.Exception - any error.

evolve

public Solution evolve(java.lang.String solutionName,
                       Solution evolveWith)
                throws java.lang.Exception

Combine the existing solution with the new solution.

Parameters:

solutionName - the name for the new solution.

evolveWith - the solution to evolve with.

Returns:

a new solution that is a mutation of both solutions.

Throws:

java.lang.Exception - any error.
