Knight moves in chess5/19/2023 ![]() ![]() The 8 power 8 is not the correct number to use in the outer loop, because you can't return to a previous point (after each move you only have 7 possible moves, not 8).Īs a test of performance I suggest you create this very small program and time it, this will give you a baseline for the most you can optimize your current solution. The website that pointed to clearly states that Brute Force solutions don’t work well for this problem. This type of programming is sometimes known as a BRUTE FORCE algorithm. The knight is the only piece in chess that can jump over another piece It moves one square left or right horizontally and then two squares up or down vertically, OR it moves two squares left or right horizontally and then one square up or down verticallyin other words, the knight moves in an 'L-shape. Your outer loop is forcing the program to go through 16.7 Million iterations of the loop, it's not clear how many times the inner loops execute. I'm looking for performance improvement in the Dvijenie method because all the combination switching is happening there. The methods ValidenRed and ValidnaKolona are checking if the Knight has already been on that spot. The Knight must NOT repeat a column or a row. Public override int GetHashCode(List list) If (l1 = null || l2 = null) return false Public override bool Equals(List l1, List l2) Private static readonly string redoveBukvi = ", minCount) Private static readonly int duska = new int On a slower machine it will probably take even longer. It's a lot but it really takes a lot of time, 25-30 secs or so. Since the Knight can make a total of 8 different turns that makes all possible turns \$8^8\$ which is 16.7 million variations. There is a solution but it would require some refactoring: Create a ChessMove class that stores a row and a column move (integers) Add a ChessMove to store all possible moves that your knight can possibly do Refactor the move method. It's all working, however, I'm not satisfied with the time it takes to calculate it. Int move = moves.get(new Random().nextInt(moves.I'm creating a console application that takes as input starting column and starting row, also the ending column and the ending row and it's going to output all the possible way's to get to that point and also highlight the best turn/s. List and Random APIs go hand in hand: //List moves =. The easiest way to randomise your move is to create a list of valid moves for a given position of the knight and then select one at random. ![]() If (canMove(nextRow, nextCol)
