I was trying to implement a solution for knight tour problem. I faced an interesting issue. I would like to know the reason for the behavior. This is the code – it works fine. Now we could run this, starting with knight position as (2, 2) in the matrix When i tried to run the starting position as (0, 0)

java recurison – Need help for solving backtracking Knight’s Tour
I am working on the Knight’s Tour problem. In my program the user can select a number n equal to 3 or higher. The number will determine the table’s size by n*n in a two-dimensional array. Then the knight will start it’s tour based on the starting points given by the user as long as they are …
Recursive Java programming, Knight’s Tour driving me nuts
I’ve been working on a school project and can not figure out the problem. The problem that the knight jumps back where it was in the the last step when a dead end occurs. I’ve added the output for a 4×4 test and you can clarly see that the knight jumps back to turn number 11 when it sees that
In the knights tour challenge, from the coordinates the player is currently on to show the user where they can move
This is from my attempt at the knights tour game, and what I was trying to do here was show the user what moves they could make from whatever position they are in, in the array. The problem arrives with NextPos[x+1][y-2]!=null in the if statement, as the exception java.lang.ArrayIndexOutOfBoundsException: -2 …
Knight’s Tour random move picker not working
I am working on randomizing which move my knight takes in my knight’s tour code. For some reason though, my switch statement always goes to default, instead of executing a possible move. I know my possible moves methods work because I have separately ran firstMoveChoice() on it’s own and it worked…
Knights tour – results in an infinite loop and i can’t figure out why
I’m trying to solve the knight’s tour problem using backtracking. I think the algorithm I have should work. I’ve tried but I can’t figure out why it isn’t working. It results in an infinite loop. However if I comment out the line that back track solutionBoard[dst.x][dst.y]=-1; it…
Can someone help me with this knight’s tour code?
The code seems fine to me, but the output is too short and the answer is no when it should be yes (starting at a,0, the knight should be able to tour the entire board) By the way, the reason my positionsVisted array is [9][9] is because I wanted the values to be 1-8, to match the output. This is

Knight’s tour depth-first search infinite loop
I’m trying to solve the knight’s tour problem using a depth-first search algorithm. The algorithm seems te be looping whenever it has two choices that both result in a dead end. I understand that this is caused because the algorithm resets the ‘wasVisited’ boolean to false again whenev…
StackOverflowError when running my “Knight’s Tour” (it’s pretty much finished otherwise)
I’m trying to make a program that goes through all squares of a chessboard (size doesn’t really matter, but for now it’s 6×6) with a knight, called a “Knight’s Tour” check it out on wiki. The tour is supposed to be closed, which means the knight on the last visited squ…
