Billionnet and S. Elloumi) So, this is a critical issue in dynamic programming. Think about it when you do the assignment, okay? Now when you do the branch and when you implement a branch and bound algorithm, space is not an issue, okay? So, what is really an issue, well in general, okay, so it depends also on the search strategy.

In a branch and bound tree, the nodes represent integer programs. Each integer program is obtained from its . parent node by adding an additional constraint. For example, IP(4) is obtained from its parent node IP(2) by adding the constraint x 2 = 0. Instead of brute-force using dynamic programming approach, the solution can be obtained in lesser time, though there is no polynomial time algorithm. Let us consider a graph G = (V, E), where V is a set of cities and E is a set of weighted edges. An edge e(u, v) represents that vertices u and v are connected.
