city.java

一个java的小程序,用SOM网络解决的是TSP问题.问题的大小可以自由变化,随机生成权值

public class City{
	
	public double x,y;
	public int update,choose;
	
	public City(double x,double y){
		this.x = x;
		this.y = y;
				
		update = 0;
		choose = 0;
		
	}
	
	public double dist(City c){
		double dx = this.x - c.x;
		double dy = this.y - c.y;
		
		return Math.sqrt(dx*dx + dy*dy);
		
	}
	
}
