Solar photovoltaic (PV) systems often encounter a problem called partial shading condition (PSC), which causes significant decrease in the system’s output power. To address this issue, meta-heuristic algorithms (MHAs) can be used to perform maximum power point tracking (MPPT) on multiple-peak P-V curves due PSCs. Particle swarm optimization was one of first MHA methods implemented for MPPT. How...

The aim of this paper is to show that the artificial gorilla troops optimization (GTO) algorithm, as an optimizer, can cope with test functions such CEC2019, and also best optimize three bar truss design problem a constrained problem. As method, two statistical measures values provided by algorithms standard deviation showing distance between were studied. At same time, convergence rate compare...

We propose a new method to constrain the location of microlensing objects using EAGLE (Extremely Amplified Gravitational LEnsing) events. We have estimated the rate of EAGLE events by taking the finite-source effect into account. We found that the EAGLE event rate for using a 1-m class telescope whose limiting magnitude is V ∼ 21 is the same as or higher than that of the ordinary microlensing e...
