The chapter focuses on Genetic-Fuzzy Rule Based Systems of soft computing in order to deal with uncertainty and imprecision with evolving nature for different domains. It has been observed that major professional domains such as education and technology, human resources, psychology, etc, still lack intelligent decision support system with self evolving nature. The chapter proposes a novel framework implementing Theory of Multiple Intelligence of education to identify students’ technical and managerial skills. Detail methodology of proposed system architecture which includes the design of rule bases for technical and managerial skills, encoding strategy, fitness function, cross-over and mutation operations for evolving populations is presented in this chapter. The outcome and the supporting experimental results are also presented to justify the significance of the proposed framework. It concludes by discussing advantages and future scope in different domains.
TopIntroduction
Soft Computing techniques employ Artificial Intelligence techniques such as Fuzzy Logic (FL), Genetic Algorithm (GA), Artificial Neural Network (ANN), etc. to provide efficient and feasible solutions in comparison with traditional computing (hard computing). Out of various Soft Computing techniques, Fuzzy Logic is the most important technique to handle imprecision and uncertainty. With a notion of linguistic variable and their relative fuzzy membership functions, representation of knowledge can be made better and human oriented. However, major limitation of FL based systems is lack of self learning and parallel computation. Given a big set of data, FL based system does not offer generalized rules or evolve solutions. This leads to the hybridization of Fuzzy Logic with Soft Computing technology that supports learning and evolution. Genetic Algorithm is one such example technique that supports automatic evolution. Clever combinations of genetic algorithm and fuzzy logic offer advantages of both the fields. The proposed chapter presents a general architecture and evolving process using genetic and fuzzy hybridization.
Major goal of education is to increase level of intelligence in every individual to progress in all areas. Technological advancements increase the efficiency of decision making and problem solving. To deal with real life problems, certain level of intelligence is essential for every individual. Genetically, individuals are blessed with multiple types of intelligence in different capacities; however results of many researchers have shown that appropriate training and development methods can increase the level of intelligence by utilizing instructional technologies. Theory of Multiple Intelligence is pioneer among available theories to identify and enhance human intelligence. According to this theory, every human being has different types of intelligence. There are many computer based applications developed to enhance different types of intelligence using the theory of Multiple Intelligence. The proposed application considers a novel approach of automatic evolution of fuzzy rule base using genetic algorithm in order to analyze technical and managerial skills of human being.

The chapter concludes with the scope and applications of the proposed work to other application areas.
Hard Computing and Soft Computing
Hard Computing is basically conventional computing. Akerkar, & Sajja (2008) state that Hard Computing techniques deal with precise, complete and full truth based system. It is capable of solving the problem which requires a precisely stated analytical model but at the same time it consumes a lot of computation time to handle real life problems dealing with imprecise and uncertain information. There are various analytical models available for handling predetermined requirements of real life problems but at the same time, it has been observed that following types of real world problems exist in a non ideal environment (Cordon et al., 2001).
- •
Pattern Recognition problems e.g. handwriting, speech, objects, images;
- •
Mobile robot coordination, control systems;
- •
Classification, forecasting, etc.
Hence, there is always a requirement of computational methods which can be suitable to handle problems that are difficult to be modeled in a predefined manner.
