Path planning is among the essential qualities of an autonomous robot. The ability to build a collision-free pathway from pre-defined point another known as path planning. There are variety approaches offered, all which vary depending on search pattern and map representation method. In this study, four robust algorithms, namely: Probabilistic Roadmaps (PRMs), A-star, Rapidly Exploring Random Trees (RRTs), Generalized Laser Simulator (GLS), were simulated their performance was measured...

Abstract Multi‐level inverters are widely used in high‐voltage and high‐power applications due to the increasing demand for renewable energy. This study proposes a novel single‐phase reduced switch multi‐level inverter topology that generates 11 levels of output voltage steps, operates asymmetric mode, uses fewer power electronic switches with efficient switching control. To optimize inverter's performance, Moth Flame Optimization (MFO), Particle Swarm (PSO), Whale Technique (WOA) utilized...
