Prolog maze solving algorithm

I want to implement a maze solving algorithm in Prolog. Therefore i searched for some maze solving algorithms and found the following: http://www.cs.bu.edu/teaching/alg/maze/ FIND-PATH(x, y): if (x,y outside maze) return false if (x,y is goal) return true if (x,y not open) return false mark x,y as part of solution path if (FIND-PATH(North of x,y) == true) return true if (FIND-PATH(East of x,y) == true) return true if (FIND-PATH(South of x,y) == true) return true if (FIND-PATH(West of x,y) == true) return true unmark x,y as part of solution path return false I already build a matrix in prolog,

Prim's algorithm for generating a maze: Getting the neighbour cell

I'm basing a maze generator program on the Prim's algorithm: This algorithm is a randomized version of Prim's algorithm. Start with a grid full of walls. Pick a cell, mark it as part of the maze. Add the walls of the cell to the wall list. While there are walls in the list: Pick a random wall from the list. If the cell on the opposite side isn't in the maze yet: Make the wall a passage and mark the cell on the opposite side as part of the maze. Add the neighboring walls of the cell to the wall list. If the cell on the opposite side already was in the maze, remove the wall from the list. (from

Which Procedure we can use for Maze exploration BFS or DFS

I know we can use DFS for maze exploration. But I think we can also use BFS for maze exploration. I'm little bit confused here because most of the books and articles that I've read had used DFS for this problem. What I think is that the Best Case time complexity of DFS will be better as compared to BFS. But Average and Worst Case time complexity will be same for both BFS & DFS and thats why we prefer DFS over BFS. Am I right or I'm having some misconception They have similar running time , but either may greatly outperform the other on any given problem simply due to the order in which the

Recursive Algorithm for 2D maze?

(This is not a duplicate) We have a 2D maze surrounded by X on all 4 sides and there are inner blocks too. All these characters of the maze is stored in 2D array. The program must find the path from start 'S' to goal 'G'. For this, a boolean method called 'solve(int row, int col) is uses and is initialized with row and column index of 'S'. The algorithm must be recursive. It should return true if its able to find the path to 'G' and false other wise. Here's how I tried to approach this problem which shows "partial correct result". public boolean solve(int row, int col) { char right = this

I am working or understanding how to create a simple java 2d maze that should look like this: int [][] maze = { {1,1,1,1,1,1,1,1,1,1,1,1,1}, {1,0,1,0,1,0,1,0,0,0,0,0,1}, {1,0,1,0,0,0,1,0,1,1,1,0,1}, {1,0,0,0,1,1,1,0,0,0,0,0,1}, {1,0,1,0,0,0,0,0,1,1,1,0,1}, {1,0,1,0,1,1,1,0,1,0,0,0,1}, {1,0,1,0,1,0,0,0,1,1,1,0,1}, {1,0,1,0,1,1,1,0,1,0,1,0,1}, {1,0,0,0,0,0,0,0,0,0,1,0,1}, {1,1,1,1,1,1,1,1,1,1,1,1,1} }; Ones this has been created the idea is to set a starting point and goal point and by using recursive depth first find the path. but must say i am having difficulties to create the maze.

Creating a maze solving algorithm in Java

一笑奈何 提交于 2019-12-03 07:14:10
问题 I've been assigned with the task of creating a maze solver in Java. Here's the assignment: Write an application that finds a path through a maze. The maze should be read from a file. A sample maze is shown below. O O O O O X O X X O X O O X O X O O X X X X X X O O X O X X X X O O X O O O O O O O X X O X X X O The character 'X' represents a wall or a blocked position and the character 'O' represents an open position. You may assume that the entrance to the maze is always in the lower right

What is the algorithm for generating the maze in the game Netwalk?

What is the algorithm for generating the maze in the game Netwalk ? The source code is available at Google Code, so you can read it for yourself and find out! The maze is generated by the function generate_maze in game.c , lines 78ff. Update: try the demo! Netwalk generates a maze by running a randomized version of Prim's algorithm to find a minimum spanning tree . Prim's algorithm iteratively grows a tree once branch at a time, starting from a source node (or nodes: in this case, the "server", the dark blue double-height box). At any given point in the running of the algorithm, the data

Implementing a randomly generated maze using Prim's Algorithm

I am trying to implement a randomly generated maze using Prim's algorithm. I want my maze to look like this: however the mazes that I am generating from my program look like this: I'm currently stuck on correctly implementing the steps highlighted in bold: Start with a grid full of walls. Pick a cell, mark it as part of the maze. Add the walls of the cell to the wall list. While there are walls in the list: **1. Pick a random wall from the list. If the cell on the opposite side isn't in the maze yet: Make the wall a passage and mark the cell on the opposite side as part of the maze.** Add the

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I'm trying to get my code to read from a text file that's contents involve: (text file is called maze1.txt) 5 5 %%%%% S % % % % % % E %%%%% However whenever I attempt to run the program I receive a segmentation fault which I think has something to do with how I'm using malloc.
