Branch-and-bound mainly addressesoptimization problems, because bounding is often based on numerical comparisons. TSP that uses the route length as the bound is a classical application; however, it can also be applied to some decision problems. In these cases, the bounding criteria are often restr...

So, one important contribution of our work is that we found a configuration and an efficient implementation of this configuration allowing to make the combination of clause learning and BnB effective for MaxSAT, as presented in this paper. 译文:因此,我们工作的一个重要贡献是,我们找到了一种配置和...
Branch and Bound (B&B) is a problem-solving technique which is widely used for various problems encountered in operations research and combinatorial mathematics. Various heuristic search procedures used in artificial intelligence (AI) are considered to be related to B&B procedures. However, in the ...
Mixed integer linear programs are commonly solved by Branch and Bound algorithms. A key factor of the efficiency of the most successful commercial solvers is their fine-tuned heuristics. In this paper, we leverage patterns in real-world instances to learn from scratch a new branching strategy opti...

A potential solution to CED is searching over all possible pairs of segments, which would incur a prohibitive quartic cost. In this paper, we propose an efficient branch-and-bound (B&B) framework that avoids exhaustive search while guaranteeing a globally optimal solution. To this end, we ...
