Optimal Adaptive Strategy Decision-Making Method Based on Gapso Algorithm

Abstract

The invention provides an optimal adaptive strategy decision-making method based on a GAPSO algorithm and is to solve the technical problem of low decision-making efficiency under the condition where the number of strategies in an adaptive strategy space is huge in the prior art. The method comprises the following realization steps: 1) obtaining a decision-making requirement of an adaptive system; 2) establishing the adaptive strategy space; 3) constructing a fitness function; 4) carrying out calculation on the adaptive strategy space by utilizing crossover and mutation of a GA algorithm to obtain an intermediate strategy space, selecting an adaptive strategy corresponding to an optimal fitness function value from the intermediate strategy space by utilizing the GA algorithm and adding the selected adaptive strategy to a target strategy space, updating the residual adaptive strategies in the intermediate strategy space through a PSO algorithm and adding the update result to the target strategy space to obtain the target strategy space; and 5) obtaining an optimal adaptive strategy. The method has the advantages of high decision-making efficiency, wide range of application and being capable of preventing conflicts between the adaptive strategies.
