We study the performance of parallel best-bound-first branch-and-bound algorithms, in which several nodes with least lower bounds are expanded simultaneously. It is well known that anomalies may occur in the execution of a parallel branch-and-bound algorithm. We show conditions under which anomalies are guaranteed not to occur when the number of processors is doubled, or not even doubled.
