Due to its robust search mechanism, Gravitational algorithm (GSA) has achieved a lot of popularity in different research communities. However, stagnation reduces searchability towards global optima for rigid and complex multi-modal problems. This paper proposes GSA variant that incorporates chaos-embedded opposition-based learning into the basic stagnation-free search. Additionally, sine-cosine...

Abstract In this paper, I review the latest results by LIGO-Virgo-Kagra Collaboration for targeted search of continuous gravitational waves (CWs) from 236 pulsars. First, present an overview types CW search. Then, show obtained using data third observing run LIGO and Virgo detectors combined with second run. No evidence has been found but it is possible to set upper limits on amplitude pulsar e...
