A study of fluctuations and confidence of implementation in genetic algorithm optimized network in data centre
Study of fluctuation in genetic algorithm has been a sub-objective in genetic algorithm implementations. The reliability of genetic algorithm may vary based on implementation case, hence it is necessary to investigate its performance pattern for each implementation case. The purpose of this study is...

Study of fluctuation in genetic algorithm has been a sub-objective in genetic algorithm implementations.

Our findings agree with the nature of genetic algorithm and other previous researchers, where it is found that the fluctuation of fitness values in our case happened randomly in general, but it had higher probability with small population sizes.
