چکیده
In this paper a modiication of a standard parallel genetic algorithm (SPGA) is introduced which can be run eeciently on diierent types of parallel computers. The purpose of the algorithm is to nd optimal morphological lters for grey scale image processing tasks. The structure of the developed General Parallel Genetic Algorithm (GPGA) is based on a new subpopulation model which uses an integral load balancing and soft synchronization mechanism. It is designed to lead to good parallelization eeciencies even on distributed workstation clusters with multiuser operating systems. This is especially important for user groups which have no access to massively parallel computers to speed up their algorithms. Run time results from tests on a massively parallel computer and a workstation cluster are shown.

متن کاملA Hybrid Unconscious Search Algorithm for Mixed-model Assembly Line Balancing Problem with SDST, Parallel Workstation and Learning Effect
Due to the variety of products, simultaneous production of different models has an important role in production systems. Moreover, considering the realistic constraints in designing production lines attracted a lot of attentions in recent researches. Since the assembly line balancing problem is NP-hard, efficient methods are needed to solve this kind of problems. In this study, a new hybrid met...
متن کاملAdaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
