A fusion algorithm of swarm intelligence and its application in emergency services facility location

In order to solve the problem of prematurity of swarm intelligence algorithm and slow speed of convergence of bacterial forging algorithm, an algorithm is proposed, which fuses quantum particle swarm together with bacteria foraging optimization. After considering the advantages of bacteria foraging optimization, quantum computing theory and particle swarm optimization, the proposed fusion algorithm takes the bacterial foraging algorithm as the main body and embedded quantum evolutionary algorithm and particle swarm optimization algorithm into it, thus improving the performance of the algorithm greatly. Through solving and validating the three criteria functions, the results show that the proposed fusion algorithm improves convergence precision and speed. Finally, the proposed algorithm is used to solve public health emergency service facility location problem and achieves good results, proving its effectiveness.
