Embodiment Construction

[0036] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0037] In the method of the present invention, the division of the algorithm search phase is based on the diversity of food sources. The metrics used for diversity are as follows:

[0038]

[0039] where N is the number of food sources, d(x i ,x k ) is the Minkowski distance between food source i and food source k:

[0040]

[0041] where is x i and xk two feasible solutions (food sources), and x i,j and x k,j are their jth components respectively, D is the number of independent variables, and q is a variable parameter related to the optimization problem. When q=1, it is the Manhattan distance that can be used for discrete problems; when q=2, it is the Euclidean distance that can be used for continuous problems.

[0042] Note that the diversity of food sources is inversely proportional to the number of iterations, and the shape of the...

Abstract

The invention discloses an artificial bee colony optimization method based on feasible solution information exchange, and the method employs different information exchange strategies at different stages of a bee colony. In the method, the exchangeable information is from a current population, and is automatically replaced along with the continuous evolution of the method. According to the invention, the method achieves different information exchange search strategies for foraging bees at different stages, and automatically adjusts the searching and development capability of the foraging bees. The method has the quicker and more effective function optimization performance under the same calculation consumption conditions.

Description

technical field [0001] The invention belongs to the technical field of artificial bee colony algorithm, and in particular relates to an artificial bee colony optimization method based on information exchange of feasible solutions. Background technique [0002] Optimization problems come from people's real life, such as resource allocation, letter delivery, logistics site selection, engineering, civil and military equipment design and other fields. Optimization methods can be used to solve these problems and provide good solutions to improve people's survival and living standards and improve the efficiency of the use of limited resources. However, the models of most optimization problems are difficult to solve, and it has even been proved that it is difficult to find a satisfactory solution under the condition of limited resources and time. Therefore, people are always committed to proposing a variety of optimization methods, extracting potential factors and prior knowledge ...
