Abstract Despite the robust cosmological and astrophysical evidence confirming the existence of a non-baryonic matter component in the Universe, the underlying nature of Dark Matter (DM) remains a mystery.Among the several possible scenarios, light DM candidates thermally produced in the early Universe are especially interesting, since their abunda
For clustering problems based on Guitar Accessories the model of mixture probability distribution separation, we propose new Variable Neighbourhood Search algorithms (VNS) and evolutionary genetic algorithms (GA) with greedy agglomerative heuristic procedures and compare them with known algorithms.New genetic algorithms implement a global search st
The spread of the COVID-19 pandemic has been considered as a global issue.Based on the reported cases and clinical data, there are still required international efforts and more preventative Sweatpants measures to control the pandemic more effectively.Physical contact between individuals plays an essential role in spreading the coronavirus more wide
