六个第一比赛，得到前三，然后这三个的小组第二替换他们在和另外三个第一比赛
再次得到前三

不过ms不严密

@ 蔡晖

事实上这个问题，我在计算前也考虑过，确实有误差，不过就像 wqx 说的，只要误差可接受就可以了，像这里的误差相对于实际结果而言是比较小的，可以接受。

@ wqx

关于红字部分，我在算式前面的括号里注明了，10 和 100 是原来算式里就有的，但我觉得不该加，所以就用红色标记了一下，可能导致你误以为是我强调要加上的...

关于 CLRS，我目前正在读，不过感觉好难啊，好多课后题都不会...
如果可能，希望能和你交流一下^_^。

非常感谢您的回复，其实在不久之后就在小百合上找到了这个方法，不过上不来，没法记录，我已经把该方法写了一篇后续，在 http://www.cnblogs.com/ScorpioLove/archive/2007/01/11/617585.html。

再次感谢 ^-^

log10(1) + log10(2) + …… + log10(1000) = log10(0.xyz) + N
M.lmn = -0.abc + N
then
N = M + 1

等号左边的加法很容易算出M

while (prev_permutation(v.begin(), v.end()))
{
PRINT_ELEMENTS( v, "");
}
的做法应该效率很低，应该为0(N*(N!))
