S people, N bins, each person has a given subset of bins he can cover, each person is given t balls. Question: What is the maximum value of the minimum number of balls per bin? i.e., allocate balls to maximize the minimum number of balls per bin, then compute the optimal minimum number.

GNU Emacs, version >= 22.1 你打开一个文件,自己移动光标到你想要查询的那个字符,然后按Control x,接着 按=,你就会在echo area看到这个字符的简单信息。如果要知道更加详细的信息, 按Control u然后Control x然后=。 要是嫌这个键组合太麻烦,你可以很容易的在.emacs里头定制一个简单的键组合。 这个elisp函数叫做describe-char。 如果你有心情花上半个小时,你还可以写一个minor mode,自动在echo area里显示 当前字符的属性。当然,前提是你得懂一点elisp ...
