General branch and bound, and its relation to A∗ and AO - Nau, V, et al. - 1984 () Citation Context ...tegy has to interact with the load balancer. One solution is to use a generic search algorithm. This concept has previously been used for didactic purposes [2] or for the ...
The no-wait constraint occurs when two consecutive operations in a job must be processed without any waiting time either on or between machines. For this, we have proposed two different resolution methods, the first is an exact method based on the branch-and-bound algorithm, in which we have...
In this case, the problem becomes one of selecting the tasks to be paralleled such that the total cost is minimized. This problem is formulated as a mixed integer programme, and a branch and bound algorithm is presented for its solution. The structural properties of this programming problem ...

In this subsection, we first overview the general branch-and-bound algorithm and the two most crucial branching algorithms in branch-and-bound, including branching variable selection and node selection. Then, we introduce the cutting plane, which is part of the branch-and-cut method. ...

branch-and-bound conceptquadratic programming modelIn this paper, heuristic and optimal algorithms for solving the group technology problem are presented. The heuristic algorithm is based on a branch-and-bound concept. A quadratic programming model for the machine grouping problem is formulated. The A...
a branch and bound algorithm is proposed. This algorithm can handle preemption in resource leveling problem. Comparing the resource leveling problem and the preemptive resource leveling problem, it is observed that considering preemption in the problem leads to better results in the objective function....
In this paper we present experimental results for a Branch-and-Bound algorithm for the Graph Partitioning Problem showing that the traditional parallelization of a Branch-and-Bound algorithm does not always lead to an efficient parallel algorithm. The main reason seems to be lack of meaningful work...
