“…The extensive experimental work in the paper shows that the proposed BPINF can improve the performance of FLAT when applied to many datasets with the variant product of lengths between 25,000 and 21,000,000. BPINF is impartially compared to other known hybrid techniques in literature such as integrated PSO with Ions Motion Optimization (IMO-PSO) (Issa & Abd Elaziz, 2020), Adaptive Sine Cosine Optimization (ASCA-PSO) [9], BA-Cuckoo Search Algorithm (CSA) ( Shehab, Khader, Laouchedi, & Alomari, 2019 ), BA-Differential Evolutionary (DE) ( Yildizdan & Baykan, 2020 ) and two different versions of BA-PSO ( Ferdowsi et al, 2019 , Manoj et al, 2016 ). Moreover, the protein of COVID-19 is investigated against other five viruses, and the LCCS results are reported for many hybrid techniques, as well as the standard SW algorithm.…”
