Abstract: The N-Queen problem is an interesting and complex combinatorial problem that has proved to be challenging for mathematicians, computer scientists, and other experts for a while now. The main ...

ABSTRACT: In this paper, we consider chessboard graphs in higher dimensions and the number of edges of their corresponding graphs. First, we solve for the number of edges for some of the chessboard ...

Virtual threads, revealed in Java's Project Loom and generally available with the Java 21 LTS, promise unparalleled scalability, simplified asynchronous coding and more efficient resource utilization.

The N Queen is the problem of placing N chess queens on an N×N chessboard so that no two queens attack each other.

The N Queen is the problem of placing N chess queens on an N×N chessboard so that no two queens attack each other. For example, the following is a solution for the 4 Queen problem.

Abstract: In this paper, a solution is proposed for n-Queen problem based on ACO (ant colony optimization). The n-Queen problem become intractable for large values of `n' and thus placed in NP ...
