Class SMICDdoMain

java.lang.Object

org.ddolib.examples.smic.SMICDdoMain

public class SMICDdoMain
extends Object

The Single Machine with Inventory Constraint (SMIC) with Ddo. The SMICDdoMain class provides the entry point for solving instances of the Single Machine with Inventory Constraint (SMIC) problem using the Decision Diagram Optimization (DDO) approach.

This main program performs the following steps:

• Loads a SMIC instance from a data file (default: data/SMIC/data10_2.txt);
• Builds a DdoModel that defines the problem, relaxation operator, ranking function, lower bound estimator, and dominance relations between states;
• Specifies a frontier management policy (SimpleFrontier) with a CutSetType.Frontier strategy;
• Executes the optimization via Solvers.minimizeDdo(DdoModel, java.util.function.BiConsumer);
• Prints the resulting solution and search statistics.

Usage:

   java SMICDdoMain [instanceFile]
 

If no file is provided as an argument, the program defaults to data/SMIC/data10_2.txt.

Example:

   java SMICDdoMain data/SMIC/data20_3.txt

Method Details

main

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

Entry point of the SMIC solver using the Dynamic Decision Diagram Optimization (DDO) algorithm. Initializes the problem instance, builds the DDO model, and executes the optimization.

Parameters:

args - command-line arguments; the first argument may specify the path to the SMIC instance file. If omitted, the default instance data/SMIC/data10_2.txt is used.

Throws:

IOException - if an error occurs while reading the instance file.
