A new metaheuristic optimization algorithm based on COVID-19: mathematical model and application to pandemic control

Abstract This paper introduces the COVID-19 optimization algorithm (COA), a novel metaheuristic inspired by the dynamical processes of the SARS-CoV-2 pandemic, including viral transmission, quarantine measures, recovery, and mutation. COA models the search for optimal solutions t...

Nil-prime ideals of a commutative ring

Let R be a commutative ring with identity and N(R) be the set of all nilpotent elements of R. The aim of this paper is to introduce and study the notion of nil-prime ideals as a generalization of prime ideals. We say that a proper ideal P of R is a nil-prime ideal if there exists...
