Abstract
A procedure to improve the lower and upper bound for the optimal objec tive function value of a minimization problem is presented. The proced ure is based on an approximation scheme. Properties of this approximat ion scheme are established on which the correctness and effectiveness of the bound improvement procedure are based. The procedure is applied to improve the computational complexities of approximation algorithms for several single and parallel machine scheduling problems.
