两个对象i和j之间的相异性可以根据不匹配率来计算:d(i,j) = (p-m)/p;其中,m是匹配的数目(即i和j取值相同状态的属性数), 而p是刻画对象的属性总数。相似性d(i,j)=1-d(i,j); 对于对称的二元属性,每个状态都同样重要。基于对称二元属性的相异性称做对称的二元相异性。d(i,j)=(r+s)/(q+r+s+t);非对称的二元属性,两个状态不是同等重要的,非对称的二

网上的题解几乎都是一样的:d(i, j, 0)表示前i行前j列,第(i, j)个格子向左运输能得到的最大值。d(i, j, 1)是第(i, j)个格子向上运输能得到的最大值。但是有一个很关键的问题没有解释:某个格子中的A矿或者B矿一定有其中一种能够运出来吗?有没有可能这个格子没有修建管道,仅仅是为了...
