Developmental plans of the country emphasize on the exports-focused growth strategy, and export diversification is one of the most appropriate policies in this area. Export diversification moves from primary goods to industrial goods. Yet, export diversification, according to the principles of international trade, must be based on comparative advantage until to change value-added. Changes in th...

This paper presents a novel differential evolution algorithm (called CCDE) using self-adaptive scaling factors, chemotaxis by BP technique, and cooperative strategy to enhance the performance of traditional DE algorithm. The CCDE consists of modified mutation strategy which is implemented from each individual and includes the momentum of each individual, the self-adaptive scaling factor strateg...

Since the advent of evolution strategies many attempts have been done to improve the mutation operator [7]. The first enhancement could be seen in the introduction of a flexible step size. As a logical consequence later n step sizes, one per variable, were used. Highest flexibility is achieved with the correlated mutation but also quadratic growth of the number of strategy parameters [8]. A new...
