Abstract

The invention relates to a bat algorithm and a system, belonging to the field of data processing, and particularly relates to a single target optimization problem method integrating explosion strategy, opposition-based learning and bat algorithm and a system. In the optimization process, the opposition-based population of each bat in the bat algorithm is obtained by opposition-based learning, andthe elite selection is performed on the two populations, thus the diversity of the population is increased, and the global search ability is improved, the local optimal solution is avoided, the explosion strategy is added during the flight process, thus the local exploration ability of the algorithm is improved, and the optimal solution is more accurately searched. Through the simulation test of 12 typical test functions and knapsack problems, it is proved that DGOBA has higher efficiency for solving continuous and discrete optimization problems.

Description

technical field [0001] The invention relates to a single-objective optimization method, a bat algorithm, an explosion strategy and a reverse learning strategy of a firework explosion algorithm, and belongs to the field of data processing, and specifically relates to a single-objective optimization problem method combining an explosion strategy, reverse learning and a bat algorithm and system. Background technique [0002] Bat Algorithm (BA) is a novel optimization algorithm developed by simulating the biological characteristics of bats searching and preying on prey through ultrasonic waves in nature. It was first proposed by Yang X.S. The algorithm has the characteristics of simple model, fast convergence speed, potential parallelism and distribution, etc. Similar to other meta-heuristic algorithms, the basic bat algorithm is also easy to fall into local optimum, premature convergence, and slow convergence speed in the later period. question.
