Special Issue on Parallel Soft Computing Techniques in High Performance Computing Systems
Nowadays, there is a need to solve more and more complex optimization problems in industry, science, engineering, and many other domains. Soft computing techniques are highly appropriate methods to deal with such complex problems (which cannot be tackled with exact methods) with reasonable computational effort. Additionally, due to the growing complexity and computational demands of such problems and the widespread availability of powerful parallel architectures (GPUs, multicore CPUs, clusters, grids, and clouds), parallel soft computing algorithms arise as highly appropriate tools to handle these problems.
This special issue focuses on novel advances in parallel soft computing algorithms and their application to the resolution of complex real-world problems to find accurate solutions in reasonable time. We look for high quality publications proposing parallel soft computing techniques designed for multi-core processors, GPUs, and other large High Performance Computing systems as clusters, grid or cloud computing to solve complex real-world problems. Additionally, works proposing novel soft computing/meta-heuristic /parallel algorithms applied to solve complex problems in the context of clusters, grid or cloud computing are of interest too.
