Gaussian Quantum Bat Algorithm with Direction of Mean Best Position for Numerical Function Optimization

الملخص EN

Quantum-behaved bat algorithm with mean best position directed (QMBA) is a novel variant of bat algorithm (BA) with good performance.

However, the QMBA algorithm generates all stochastic coefficients with uniform probability distribution, which can only provide a relatively small search range, so it still faces a certain degree of premature convergence.

In order to help bats escape from the local optimum, this article proposes a novel Gaussian quantum bat algorithm with mean best position directed (GQMBA), which applies Gaussian probability distribution to generate random number sequences.

Applying Gaussian distribution instead of uniform distribution to generate random coefficients in GQMBA is an effective technique to promote the performance in avoiding premature convergence.

In this article, the combination of QMBA and Gaussian probability distribution is applied to solve the numerical function optimization problem.

Nineteen benchmark functions are employed and compared with other algorithms to evaluate the accuracy and performance of GQMBA.

The experimental results show that, in most cases, the proposed GQMBA algorithm can provide better search performance.
