minimise the trace of a matrix over all column permutations












1












$begingroup$


I have a 10x10 positive symmetric matrix, I need to find the optimal permutation of the columns in order to minimise the trace. I can't try all permutations because that would be a 10! problem. Any ideas on how to tackle this problem?
