this paper uses integrated data envelopment analysis (dea) models to rank all extreme and non-extreme efficient decision making units (dmus) and then applies integrated dea ranking method as a criterion to modify genetic algorithm (ga) for finding pareto optimal solutions of a multi objective programming (mop) problem. the researchers have used ranking method as a shortcut way to modify ga to d...

There has been a big interest in inducing classes of grammars in the area of machine learning. Various attempts have been carried out for automatically inferring diierent grammar classes. The symbolic nature of the grammar induction problem makes it suitable for the GP-approach. However the straightforward application of the GP method on Context Free Grammar Induction problem fails to generate ...
