In video games, pathfinding must be done quickly and accurately. Not much computational time is allowed for pathfinding, but realistic looking paths are required. One approach to pathfinding which attempts to satisfy both of these constraints is to perform pathfinding on abstractions of the map. Botea et al.’s Hierarchical Pathfinding A* (HPA*) does this by dividing the map into square sectors ...

Rhythmic spontaneous bursting activity, which occurs in many developing neural circuits, has been considered to be important for the refinement of neural projections but not for early pathfinding decisions. However, the precise frequency of bursting activity differentially affects the two major pathfinding decisions made by chick lumbosacral motoneurons. Moderate slowing of burst frequency was ...

This paper proposes a novel method to generate strategic team AI pathfinding plans for computer games and simulations using probabilistic pathfinding. This method is inspired by genetic algorithms (Russell and Norvig, 2002), in that, a fitness function is used to test the quality of the path plans. The method generates high-quality path plans by eliminating the low-quality ones. The path plans ...

Pathfinding is a very popular area in computer game development. While two-dimensional (2D) pathfinding is widely applied in most of the popular game engines, little implementation of real three-dimensional (3D) pathfinding can be found. This research presents a dynamic search space optimization algorithm which can be applied to tessellate 3D search space unevenly, significantly reducing the to...

Tower Defense is a game genre that uses pathfinding algorithm. Pathfinding way to find path from one point another; itself has many variants with different scenarios. One of these algorithms the A-Star algorithm, well- known and commonly used method for pathfinding. Another algorithm Flow Field which an not widely become topic in this following research. This research will be carried out by com...

One of the greatest challenges in the design of realistic Artificial Intelligence (AI) in computer games is agent movement. Pathfinding strategies are usually employed as the core of any AI movement system. This report will highlight pathfinding algorithms used presently in games and their shortcomings especially when dealing with real-time pathfinding. With the advances being made in other com...
