Pathfinder is a research area that focuses on developing algorithms and techniques for optimal path planning in various environments, such as robotic navigation, network routing, and game AI. Pathfinder research aims to find efficient and effective solutions for finding the shortest or safest path between two points in complex and dynamic spaces. This area of research often involves studying computational geometry, graph theory, optimization, and machine learning to create algorithms that can handle different types of obstacles, constraints, and uncertainties in path planning. Ultimately, Pathfinder research aims to improve navigation and decision-making processes in a wide range of applications, from autonomous vehicles to virtual reality simulations.
