Getting Started

This repository contains an integer programming formulation and a fix-and-optimize method to address the Sports Timetabling Problem proposed during the International Timetabling Competition of 2021 (ITC2021)

Compiling the code

This project now uses gradle. It simplifies compiling the code with its dependencies. Make sure you have access to Gurobi's Java library and just run:

• gradle build

The jar file itc2021.jar will be generated.

Usage examples:

• java -jar itc2021.jar instance.xml solution.xml
• java -jar itc2021.jar instance.xml solution.xml -validate

Requirements

• Java 16
• Gurobi 9 or newer
• Apache Commons Math library (included automatically by gradle).
