Graphical Simulation of N Queens Problem

Graphical simulation is an attempt of predicting the aspects of behavior of some system by developing an approximate model of it. Simulations have great impact on education and in training. Simulation based learning is a practical way of learning of practices that involves building connections: connections among what is being learned and what is important to the actor and the situations in which it is applied. N-Queens problem refers to the problem in which one has to place N-Queens on an n*n chess board such that no queen is attacking the other, i.e. no two queens occupy the same row, column or diagonal. Here we use graphical simulation to view various solutions to N-Queens problem. The n-queens problem is implemented by using core java. The packages used in these implementations are java.awt, java.lang, java.applet. The graphical simulation is used because n-queens problem is more complicated. It is easy for any system user or normal user to understand this problem by observing simulations. With the help of simulation the problem is explained very clearly and effectively. This will help in generating interest among perceivers because it has real time applications and will make learning better.
