Abstract Whale optimization algorithm, as a relatively novel swarm-based intelligence has been extensively utilized in numerous scientific and engineering fields. The intent of this work was to devise modified WOA based on multi-strategy, named MSWOA, address somewhat deficiencies the original WOA, such converging slowly, stagnating at local minima poor stability. First, tent map function is ad...

The whale optimization algorithm (WOA) is a popular swarm intelligence which simulates the hunting behavior of humpback whales. WOA has deficiency easily falling into local optimal solutions. In order to overcome weakness WOA, modified variant called OCDWOA proposed. There are four main operators introduced enhance search performance WOA. include opposition-based learning method, nonlinear para...

The optimal power flow (OPF) is a vital tool for optimizing the control parameters of system by considering desired objective functions subject to constraints. Metaheuristic algorithms have been proven be well-suited solving complex optimization problems. whale algorithm (WOA) one well-regarded metaheuristics that widely used solve different Despite use WOA in fields application as OPF, its eff...

In the field of wireless multimedia authentication unimodal biometric model is commonly used but it suffers from spoofing and limited accuracy. The present work pro-poses fusion features face fingerprint recognition system as an Improved Biometric Fusion System (IBFS) leads to improvement in performance. Integrating multiple traits performance improved thereby reducing fraudulent access.The pap...
