codeofroughset
粗糙集的基本算法，包括数据补齐，属性约简，值约简，规则生成，非常实用。(Rough set theory is a new mathematical approach to imperfect knowledge. The problem of imperfect knowledge has been tackled for a long time by philosophers, logicians and mathematicians. Recently it became also a crucial issue for computer scientists, particularly in the area of artificial intelligence. )
