Optimized Parameter Settings of Binary Bat Algorithm for Solving Function Optimization Problems

Abstract EN

The bat algorithm (BA) is a new bionic intelligent optimization algorithm to simulate the foraging behavior and the echolocation principle of the bats.

The parameter initialization of the discussed binary bat algorithm (BBA) has important influence on the convergence speed, convergence precision, and good global searching ability of the BBA.

The convergence speed and algorithm searching precision are determined by the pulse of loudness and pulse rate.

The simulation experiments are carried out by using the six typical test functions to discuss this influence.

The simulation results show that the convergence speed of the BBA is relatively sensitive to the setting of the algorithm parameters.

The convergence precision reduces when increasing the rate of bat transmitted pulse alone and the convergence speed increases the launch loudness alone.

The proper combination of BBA parameters (the rate of bat transmitted pulse and the launch loudness) can flexibly improve the algorithm’s convergence velocity and improve the accuracy of the searched solutions.
