The basis theorem of binary-coded genetic algorithm is scheme theorem. However ,there is not enough research on the scheme theorem of decimal coded genetic algorithm. We define the corresponding concepts and put forward the corresponding scheme theorem of the integer-coded genetic algorithm referring to the basic concepts of binary coded genetic algorithm.展开更多

But these coding strategies have their own advantages and disadvantages for the optimization of functions. In this paper a new Decimal Coding Strategy (DCS), which is convenient for space division and alterable precision, was proposed, and the theory analysis of its implicit parallelism and convergence was also discussed. We also redesign several genetic operators for the decimal code. In order to utilize the historial information of the existing individuals in the process of evolution and avoid repeated exploring, the strategies of space shrinking and precision alterable, are adopted. Finally, the evolutionary algorithm based on decimal coding (DCEAs) was applied to the optimization of functions, the optimization of parameter, mixed-integer nonlinear programming. Comparison with traditional GAs was made and the experimental results show that the performances of DCEAS are better than the tradition GAs.展开更多
