“…Many research works were based on this algorithm to solve their problems. FireFly was used to solve the mono-processors hybrid flow shop problem (Dekhici & Belkadi, 2017), flexible operation scheduling (Fuyu, Weining, & Yan, 2018), facial expression recognition (Mistry, Zhang, Sexton, Zeng, & He, 2017), home care scheduling (Dekhici, Redjem, Belkadi, & Mhamedi, 2019), biomedical engineering (BME), healthcare (Nayak, Naik, Dinesh, Vakula, & Byomakesha, 2020), and also for image analysis (Dey, Chaki, Moraru, Fong, & Yang, 2020). Some researchers stated that FA was a powerful algorithm for solving even some of the NP-complete problems (Kumar & Kumar, 2021).…”
