Some variants of GA are binary GA, real GA, messy GA, micro GA, saw tooth GA, differential evolution GA. This research article presents a real coded GA for predicting enrollments of University of Alabama. Data of Alabama University is a fuzzy time series. Here, fuzzy logic is used to predict enrollments of Alabama University and genetic algorithm optimizes fuzzy intervals. Results are compared to other eminent author works and found satisfactory, and states that real coded GA are fast and accurate.Genetic Algorithm (GA) forms a subset of evolutionary computing, rapidly growing area of Artificial Intelligence (A.I.).

A todos os meus professores, que me possibilitaram o aprimoramento do conhecimento. E, por fim, ao meu orientador, Dr. Luis Carlos Susin, pela sua paciência, conhecimento, sabedoria e humildade, orientando-me com gesto de cristão que procura se esmerar no ensino do verdadeiro conhecimento. "Se há alguma ordem de homens à qual é completamente inadequado aspirar às honras deste mundo, em especial as honras que são acompanhadas de pompa e aplauso, essa, sem dúvida, é a ordem eclesiásticaum conjunto de homens que deveriam estar inteiramente ocupados com o zelo por Deus e pelo alcance daquela glória que está à disposição dEle."

This method uses concepts of central tendencies mean and variance. This study gives a solution to the critical issue in designing of fuzzy systems, number of fuzzy sets. Proposed computational method helps in finding intervals and thereby fuzzy sets for fuzzy time series forecasting. Proposed computational method is implemented on the authentic data for the enrolments of University of Alabama, which is considered as benchmark problem in the field of fuzzy time series. The forecasted values are compared with the results of other methods to state its supremacy. Projected computational method along with Gaussian membership function gave promising results over other methods for fuzzy time series for the above said benchmark data.
