Re:一减枝超厉害，从tle到16ms acIn Reply To:一减枝超厉害，从tle到16ms ac Posted by:yuanluliao at 2010-08-07 18:50:01 > 如果有相同价值的邮票数超过4中的话可以不要再增加这种价值的邮票啊！！！！！！ 但是这就有问题了啊。 比如有五种邮票，面值都是1.记为1(1),1(2),1(3),1(4),1(5) 现在要找面值是4的分配 显然应该分配4张1，如果剪枝的话结果就是1(1),1(2),1(3),1(4), 但实际还有1(2),1(3),1(4),1(5)；1(2),1(3),1(4),1(1)等可能啊。 Followed by:
