怎样适当的评估分布式Mahout
如果没有Watchmaker程序，你将不得不创建一个实例：StandaloneEvolutionEngine。在TSP例子里，已经做好了EvolutionaryTravellingSalesman类：
private EvolutionEngine<List<String>> getEngine(CandidateFactory<List<String>> candidateFactory, EvolutionaryOperator<List<?>> pipeline, Random rng) { return new StandaloneEvolutionEngine<List<String>>(candidateFactory, pipeline, new RouteEvaluator(distances), selectionStrategy, rng);}private EvolutionEngine<List<String>> getEngine(CandidateFactory<List<String>> candidateFactory, EvolutionaryOperator<List<?>> pipeline, Random rng) { MahoutFitnessEvaluator<List<String>> evaluator = new MahoutFitnessEvaluator<List<String>>(new RouteEvaluator(distances)); return new STEvolutionEngine<List<String>>(candidateFactory, pipeline, evaluator, selectionStrategy, rng);}
