Abstract—In rough set models, tolerance relation, similarity relation and limited tolerance relation solve different situation problems for incomplete information systems in which there exists a phenomenon of missing value. If two objects have the same few known attributes and more unknown attributes, they cannot distinguish them well. In order to solve this problem, we presented two improved l...

Recently, hardware researchers have promptly begun to investigate alternative computational principles to the conventional ones. The main signs of these principles are inspiration in biology and their direct hardware implementation. Evolvable hardware, cellular computing or embryonic electronics are the most important examples. This paper describes different approaches to configuration, reconfi...
