use of evodef.EvoAlg in project SimpleAsteroids by ljialin.

the class RandomTestPlanetWars method evaluate.

public static double evaluate(SimplePlayerInterface player) {

    EvoAgent evoOpponent = new EvoAgent().setEvoAlg(evoAlgOpponent, nOpponentEvals).setSequenceLength(opponentSeqLength);
    // setting to false provides a much weaker opponent
    evoOpponent.setUseShiftBuffer(true);
    // now run a game and return the result
    gameRunner.verbose = false;
    gameRunner.reset();
