The Novel Approach of Adaptive Twin Probability for Genetic Algorithm
This work addresses performance enhancement for GA users, but it is incremental as it builds on existing twin operator concepts.
The paper tackles the challenge of balancing exploration and exploitation in Genetic Algorithms (GA) by introducing an adaptive twin probability approach, which results in increased accuracy and reduced convergence time on standard benchmark functions.
The performance of GA is measured and analyzed in terms of its performance parameters against variations in its genetic operators and associated parameters. Since last four decades huge numbers of researchers have been working on the performance of GA and its enhancement. This earlier research work on analyzing the performance of GA enforces the need to further investigate the exploration and exploitation characteristics and observe its impact on the behavior and overall performance of GA. This paper introduces the novel approach of adaptive twin probability associated with the advanced twin operator that enhances the performance of GA. The design of the advanced twin operator is extrapolated from the twin offspring birth due to single ovulation in natural genetic systems as mentioned in the earlier works. The twin probability of this operator is adaptively varied based on the fitness of best individual thereby relieving the GA user from statically defining its value. This novel approach of adaptive twin probability is experimented and tested on the standard benchmark optimization test functions. The experimental results show the increased accuracy in terms of the best individual and reduced convergence time.
