I tried to explain a smaller problem saying that the matrix is symmetric but maybe it's not helping too much. So, my specific problem is: - I have a distance matrix of two sets of elements. The two sets can have different number of elements, so the matrix is only square and symmetric when you...

One can change rows and columns independently.

Dear all, I have the following problem: I have a symmetric (non sparse) matrix, and I want to find the permutation of columns and rows that lead to have the smaller numbers in the diagonal. Anyone has a clue on how to solve efficiently this kind of problems? Thanks!
