I’m using the a* algorithm to create a rotation, but when I increase the row and col above 180, I get a stack overflow error. Anyone have any ideas? my codes, if you run this now, it will not give an error, but if you set the ROW and COL values to 180e or higher, ..

I have in C++ an implementation of an A* search, which is otherwise working fine, but has a memory leak. I’ve tried to use the CRT library to help find the leak and it seems that the SearchState objects I create are not deallocated properly, but I can’t quite figure out why. EDIT: I included ..
I’ve looked over several different implementations of A*. The current one I am using is based off of the pseudocode from the Wikipedia page. It finds the path but then the monster doesn’t move so I’m guessing it doesn’t work. It’s also incredibly slow. This is inside the update function which is called after the ..
I need to implement the following requirment, using a search algorithm(A STAR, BEST FIRST): n vehicles occupy squares (1, 1) through (n, 1) (i.e., the bottom row) of an n×n grid. The vehicles must be moved to the top row but in reverse order; so the vehicle i that starts in (i, 1) must end ..
I have been give a problem in which I am provided with user-entered matrix (rows and columns). User will also provide Start State (row and column) and the Goal State. The job is to use A* search to find the path from the start node to the goal node. A sample matrix is provided below, ..
I’m trying to implement an A* algorithm for pathfinding in my 3D grid. I’ve been following a tutorial but I’m not getting a valid path. I’ve stepped through my code to find out what’s going on, but I don’t know how to solve the problem. For the most basic test I’m just using a 2-D ..
My algorithm works almost well, but unfortunately, when it reaches a corner, it can’t move further. Can you give me some hints on what I am doing wrong? If the algorithm does not encounter obstacles, it is free to move left, right, up and down. However, if on a corner, as in the map I ..
I’m currently working on A* algorithm small project but I think there is a problem with manhattan distance. I mean, when the code equals to: inline int32 manhattanDistance(Node* startNode, Node* endNode) { int32 deltaX = std::abs(startNode->position.x – endNode->position.x); int32 deltaY = std::abs(startNode->position.y – endNode->position.y); return deltaX + deltaY; } It’s returning the path as: Valid ..
I just started to learn c++ at university, I have to create a pacman in c++. I wanted to integrate the algorithm of A. Star, I tried ^^, I think I have included it well however when the distance of the target is greater than 4, he sends me the list but not with the ..
I’m implementing A* algorithm which requires a faster query of data, the best way I could think of is Hash Tables (unordered_map in cpp) but the computation time is little high(4 micro secs for each query) for my use case. A*: A* is a Heuristic-based search method to find the optimal solution in a given ..
