public class PSAstarMain
extends Object

The Pigment Sequencing Problem (PSP) with AsTar. Main class for solving a Pigment Sequencing Problem (PSP) using the A* search algorithm.

This program loads a PSP instance (either from a specified file or from a default path), builds a corresponding model, and applies the A* algorithm to minimize the total scheduling cost.

The computed solution is printed to the console, followed by statistics about the search process.

Usage:

 java PSAstarMain [instanceFile]
 

If no instanceFile argument is provided, the default instance located at data/PSP/instancesWith2items/10 is used.

Method Details

main

public static void main(String[] args)
                 throws IOException

Entry point of the program.

This method initializes a PSProblem from the given instance file, constructs a Model for the A* search, and runs the solver using Solvers.minimizeAstar(Model, java.util.function.BiConsumer). The resulting solution and search statistics are printed to standard output.

Parameters:

args - optional command-line argument specifying the path to a PSP instance file

Throws:

IOException - if an error occurs while reading the problem instance
