Rectangular coding genetic algorithm for cascade reservoirs operation
Zhang Youquan · Journal of Hydroelectric Engineering · 2012
In traditional genetic algorithm(GA),chromosomes coding is usually in chain form that is the form of feasible solutions.This means that binary or real-number encoding may take such a chained coding and it may also be used for genetic computing.One shortcoming of the chained coding is that the length of chromosome chain will become longer when the number of decision variables increases,leading to a much lower efficiency of computation.Another is the coding difficulty caused by coupling of the upstream and downstream reservoirs,as a change in any gene of the upstream reservoir' chromosomes will result in consecutive changes in the downstream chromosomes.This paper presents an advanced GA of rectangular coding that by resolving these problems improves greatly the computation efficiency and the optimization results.A simulation example is given to verify the feasibility and validity of the proposed algorithm.
