This paper deals with the parallel implementation of the back-propagation of errors learning algorithm. We propose two mapping schemes that allow to obtain two efficient parallel algorithms implemented on the Meiko CS-2 MIMD parallel computer. The parallel algorithms, obtained from the sequential code by means of simple and well localised modifications, are based on the use of a global operator whose...
This paper deals with the exact solutions of combinatorial optimisation problems. We describe a parallel implementation of a Branch and Bound algorithm; we complete such software with heuristic schemes and we show results with reference to the well known TSP problem. We evaluate the performance by introducing the concept of implementation efficiency that allows to estimate the communication overhead...
