测试结果表明，相对于穷尽搜索方法，计算量得到明显的降低，计算时间减少约90 % ，同时只需要很少的预先计算量和额外存储量。

The test result shows that the reduction of computation is about 90% in the encoding time against full search method, and a little precomputation and extra storage are required.

通常的评价方法是用基于标准案例的测试程序对模型进行测试，但这些案例毕竟是有限的，不能穷尽所有情况。

General evaluation way is to use test program based on standard cases to test the model, but the cases are limited and do not include all instance.
