In the previous approach, by grouping genetic algorithm, an approach has been proposed for mining diverse group stock portfolio which can be used to generate various stock portfolios. However, a parameter, number of groups, should be given in advanced of that approach, and it is hard to set appropriate value. Hence, the intent of this research is to design an algorithm that can find appropriate number...
In this paper, to increase the diversity of stock portfolios, the diverse group stock portfolio mining algorithm is proposed based on the grouping genetic algorithm. Each chromosome is represented by grouping part, stock part and stock portfolio part. The fitness function that consists of portfolio satisfaction, group balance and diversity factor is designed to evaluate quality of chromosomes. The...
