A new method for discrete optimization problems

A generalized optimization system with a discrete decision space, is described, and on an optimization problem is defined which is associated with the system. A new solution method, which is called modular approach (MA), is presented to solve the optimization problem. This method extends the Morin-Marsten hybrid idea to solve troublesome problems of dynamic programming. The present method is also an extension of the branch-and-bound method using breadth-first search.
