Expeditious COVID-19 similarity measure tool based on consolidated SCA algorithm with mutation and opposition operators

Abstract

COVID-19 is a global pandemic that aroused the interest of scientists to prevent it and design a drug for it. Nowadays, presenting intelligent biological data analysis tools at a low cost is important to analyze the biological structure of COVID-19. The global alignment algorithm is one of the important bioinformatics tools that measure the most accurate similarity between a pair of biological sequences. The huge time consumption of the standard global alignment algorithm is its main limitation especially for sequences with huge lengths. This work proposed a fast global alignment tool (G-Aligner) based on meta-heuristic algorithms that estimate similarity measurements near the exact ones at a reasonable time with low cost. The huge length of sequences leads G-Aligner based on standard Sine-Cosine optimization algorithm (SCA) to trap in local minima. Therefore, an improved version of SCA was presented in this work that is based on integration with PSO. Besides, mutation and opposition operators are applied to enhance the exploration capability and avoiding trapping in local minima. The performance of the improved SCA algorithm (SP-MO) was evaluated on a set of IEEE CEC functions. Besides, G-Aligner based on the SP-MO algorithm was tested to measure the similarity of real biological sequence. It was used also to measure the similarity of the COVID-19 virus with the other 13 viruses to validate its performance. The tests concluded that the SP-MO algorithm has superiority over the relevant studies in the literature and produce the highest average similarity measurements 75% of the exact one.

Improving Parameter Estimation of Fuel Cell Using Honey Badger Optimization Algorithm

“…As mentioned before, metaheuristic optimization algorithms proved their ability to deal with various problems such as (Famouri and Gemmen, 2003). bioinformatics (Issa, 2021a;Issa and Abd Elaziz, 2020;Issa and Hassanien, 2017;Issa et al, 2018a;Issa et al, 2018b;Issa and Helmi, 2021;, control engineering (Issa, 2021b;Issa et al, 2019), passive suspension system (Issa and Samn, 2022), and digital watermarking (Abualigah and Diabat, 2021;Issa, 2018). To estimate the model parameters of the PEMFC, an efficient method compared to the existing method is needed.…”
