The mini-max spanning forest problem requires to find a spanning forest of an undirected graph that minimizes the maximum of the costs of constituent trees. In a previous work we proved this problem NP-hard. In the current paper we present three lower bounds for this problem and develop a branch-and

The most popular parallelization approach of the branch and bound algorithm consists in building and exploring in parallel the search tree representing the problem being tackled. The deployment of such parallel model on a grid rises the crucial issue of dynamic load balancing. The major question is
In this study, the two-machine bicriteria flowshop scheduling problem is addressed. The objective is to minimize a weighted sum of total flowtime and makespan. Different branch-and-bound algorithms have already appeared in the literature for this problem. In this study, a more efficient branch-and-b
