ABSTRACT
For a long time, optimization has been part of our lives and the most recent literature shows a tremendous increase of the number of articles using Revolutionary algorithms in particular Firefly algorithm (FA) and Genetic algorithm. This tendency can be observed nearly in all areas of Computer Sciences and Engineering domain. Some of them are hybridized with other techniques to discover better performance. In addition, literatures found that most of the cases that used (FA) and (GA) techniques have outperformed compare to other metaheuristic algorithms. And because of the extraordinary impact of the COVID-19 pandemic on society and business as a whole, the pandemic generated an increase in the number and range of cybercriminal attacks due to the extensive use of computer networks. As result, new risks have arisen, and improving the speed and accuracy of security mechanisms has become a critical need. The aim of this article is to give the main mechanisme of those approachs and their application alone and hybrided to solve cybercrime problems. © 2022 IEEE.
