Solving TSPLIB Instances

The file tspSolver/src/main/Main.java contains code that will run your solver on instances from the TSPLIB database. The main method of this class begins with

	public static void main(String[] args) {
		String[] problemNames = new String[]{"bier127","eil51","brd14051","ch130","ch150","d198", "d493","d657", "d1291","fl1400"};
		String problemName = problemNames[1];
		//...

Here the elements of problemNames are files in the directory sampleData/TSPLIB/ that existing code will parse for you into a problem instance. The number in the file name refers to the number of cities in the problem. You can adjust which problem is attempted by assigning a different value to problemName (by changing the index used to access problemNames, or if you prefer, typing in a file name manually). Try running your solver on a few different instances (start with smaller ones).
