In contrast to usual branch-and-bound methods, in the algorithm the upper bound of the subproblem in each node is calculated easily by arithmetic expressions. Also, a reduction operation is introduced to reduce the growth of the branching tree during the algorithm search. The proposed algorithm ...
of new data structures, we have reduced the time cost by avoiding the topological sorting in Top-MLCS, and further reduce DAG and the space consumption through the branch and bound method. As a result, a much Smaller DAG called Small-DAG than the existing ones is constructed. The ...
the solution space is often too vast to traverse. The branch-and-bound algorithm handles this problem byboundingandpruning. Bounding refers to setting a bound on the solution quality (e.g., the route length

A branch-and-bound type re- finement procedure is implemented to reduce the conservatism. We demonstrate the method on a two-state example from the literature and five-state controlled short period aircraft dynamics with and without time delay in the input to the plant. I. INTRODUCTION We...
The implementation of an excellent cutting algorithm can effectively streamline the sheet cutting process, optimize sheet utilization, minimize resource consumption, and ultimately reduce production costs for enterprises [1–3]. Based on the geometry of the items, the two-dimensional cutting problem can...
The idea is to use the genetic algorithm to improve the upper bound and thus speeding up the Branch-and-Bound while the genetic algorithm uses the content of the Branch-and-Bound stack to reduce its search space. Both methods are running in parallel and are therefore collaborating together. ...
