JBench 1

From CS227B Wiki

Below is the code which defines the JBench 1 state machine benchmark. To see people's results on this benchmark, visit state machine benchmarks.

private void testStateMachine(StateMachine sm) throws Exception {
	long time = runDepthCharges("connectfour", sm, 2000);
	time += runDepthCharges("nineboardtictactoe", sm, 1000);
	time += runDepthCharges("breakthroughsmall", sm, 1000);
	time += runDepthCharges("tictactoelarge", sm, 2000);
	System.out.println("Testing state machine took " + time + " ms");
}

private long runDepthCharges(String game, StateMachine sm, int num) throws Exception {
	sm.initialize(KifReader.read("games" + File.separator + "rulesheets" + 
                                    File.separator + game + ".kif"));
	
	long time = System.currentTimeMillis();
	for (int i = 0; i < num; i++) {

		sm.doPerMoveWork();

	return System.currentTimeMillis() - time;
}
