Abstract

The invention discloses a heuristic optimization method based on a two-line hybrid rice breeding mechanism. Search populations are classified into two classes: a maintainer line population and a sterile line population. On the basis of improvement of the genes of the sterile line population, the gene quality is improved and thus the high yield is obtained. According to the invention, the two-linehybrid rice breeding mechanism continues; the designed heuristic optimization method needs a few of parameters and the time complexity is reduced, so that the searching speed is increased while the search ability is ensured. The heuristic optimization method can be applied to the calculation process of complicated optimization problems like image processing, pattern recognition, traveling salesmanissue and resource scheduling. The high-quality feasible solution can be found out with the acceptable time costs.

Description

technical field [0001] The invention belongs to the technical field of computational intelligence, relates to a heuristic optimization method on an optimization problem, in particular to a heuristic optimization method based on a two-line hybrid rice breeding mechanism. The invention is applied in the process of solving complex optimization problems such as image processing, pattern recognition, traveling salesman problem, and resource scheduling. Background technique [0002] Since the 1970s, some evolutionary algorithms, which are completely different from the classic mathematical programming principles, have appeared one after another, trying to solve complex optimization problems by simulating natural ecosystem mechanisms or natural phenomena, such as genetic algorithms, artificial immune algorithms, differential evolution algorithms, etc. . These algorithms have greatly enriched modern optimization techniques, and also provide practical solutions to combinatorial optim...
