Abstract

The job rotation problem (JRP) is the following: Given an nxn matrix A over R@?{-~} and k@?n, find a kxk principal submatrix of A whose optimal assignment problem value is maximum. No polynomial algorithm is known for solving this problem if k is an input variable. We analyse JRP and present polynomial solution methods for a number of special cases.
