题目来源:POJ 1046 Color Me Less 题目大意:每一个颜色由R.G.B三部分组成,D=Math.sqrt(Math.pow((left.red - right.red), 2)+ Math.pow((left.green - right.green), 2)+ Math.pow((left.blue - right.blue), 2)) 表示两个不同颜色的之间的距离(以left和right为例,left和right分别为两种不同的颜色),现给出16组目标颜色,剩下的为待匹配的颜…

倍增+Floyd 题解:http://www.cnblogs.com/lmnx/archive/2012/05/03/2481217.html 神题啊= =Floyd真是博大精深…… 题目大意为求S到E,恰好经过N条边的最短路径(姑且称为路径吧,虽然好像已经不是了……) 总共只有大约200个点(很多点根本没走到,离散化一下即可)所以可以考虑Floyd算最短路. 引用下题解: 题目求i,j之间边数恰为N的最短路径(边可以重复走),我们知道线性代数中有:01邻接矩阵A的K次方C=A^K,C[i][j…

POJ 排序的思想就是根据选取范围的题目的totalSubmittedNumber和totalAcceptedNumber计算一个avgAcceptRate. 每一道题都有一个value,value = acceptedNumber / avgAcceptRate + submittedNumber. 这里用到avgAcceptedRate的原因是考虑到通过的数量站的权重可能比提交的数量占更大的权重,所以给acceptedNumber乘上了一个因子. 当然计算value还有别的方法,比如POJ上…
