Abstract: | Let twon×n matrices be given, namely a real matrixA=(aij) and a (0, 1)-matrixT=(tij). For a cyclic permutation=(i1,i2,...,ik) of a subset of N={1, 2, ..., n} we define A;T(), the cost-to-time ratio weight of, as. This paper presents an O(n3) algorithm for finding (A;T)=max A;T(), the maximum cost-to-time ratio weight of the matricesA andT. Moreover a generalised eigenproblem is proposed. |
