I\'m having trouble with a programming assignment, its a penplotter, there have been quite a few questions about it already here.
I have implemented a basic grid based A* pathfindinder in Java. I would like to make a navigational mesh/polygon based pathfinder, but the problem I have is this:
I need a good heuristic function for A star for the pen plotter/TSP, where each state of my system has:开发者_C百科
I\'m implementing a A* search algorithm but I keep running into problems with the priority queue. I have implemented a custom comparator for the priority queue according to this article
I’ve implemented and used A* several times and thought I knew everything there was to know about A*…. Until I encountered this example:
I need some help with my A* algorithm implementation. When I run the algorithm it does find the goal, but the path is definately not the shortest :-P
I have to get the (shortest)/(an optimal) distance between two points in 2D. I have to avoid shapes that are lines, that may be connected together. Any suggestion on how to represent the nodes I can t
From this link: Link If an adjacent square is already on the open list, check to see if this path to that square is a better one. In other words, check to see
I currently have an array of points (x,y) from the result of an A* pathfinding function. This array is set up so that the first index is the point closest to the character and the next one is the next
I am using A* for pathfinding in a Java project that I am working on. My attempt at implementing it though, has some issues. Not only is it slightly slow, but it sometimes runs into infinite loop issu
