摘要 本次课程设计的题目是“A星算法的演示系统”，A*算法在人工智能中是一种典型的启发式有哪些信誉好的足球投注网站算法java Abstract The topic of the course design isA star algorithm demo software, A * algorithm in artificial intelligence is A kind of typical heuristic search algorithm, this is A graphics in the plane ,have more than one node path, the algorithm of minimum through cost.it often be used in the game of mobile computing of NPC, or online games on mobile computing of BOT.The course design requirs to demonstrate the implementation process of the whole algorithm, can be single step demo, dynamic demonstration, the essence of the execution process of algorithm demo. on the basis of full understanding of the algorithm, Demonstrateing the algorithm implementation process will involve the Graph drawing, and the programming on image, obviously a high-level language has the characteristics of its development of high efficiency, Java powerful computing and graphics display function, make the image programming more simple and intuitive.This project is based on eclipses Java integrated development environment, A star algorithm demo software was designed and implemented, showing how A star algorithm of heuristic search and pathfinding.Implements set the starting point and end point, barriers, clear obstacles, directly pathfinding, single step pathfinding, dynamic pathfinding, pathfinding again, add default barrier function of these operations.the user can use the software according to their requirments, the software fully shows the execution of A star algorithm.
