Notice of Retraction Mixed-coding Differential Evolution Algorithm for Integer Programming

Mixed-coding population Differential Evolution algorithm was proposed for integer programming. Firstly, each individual in the initial population with two different fields, one is real and the other is integer, is generated. Then a new operator, boundary-handling operator, was added to the original Differential Evolution to ensure each population generated by the mutation operator and crossover operator satisfying the boundary constraints. Lastly a new mapping operator was put forward to map one real number into an integer number, which is stored in the integer field. Two initial simulation results of two integer programming with the size of 30 variables show it is effective and efficient. Mixed-coding Differential Evolution algorithm is a new effective way for solving the integer programming problems.
