Genetic-based Constraint Programming for Resource Constrained Job Scheduling

no code implementations1 Feb 2024 Su Nguyen, Dhananjay Thiruvady, Yuan Sun, Mengjie Zhang

In the proposed algorithm, evolved programs represent variable selectors to be used in the search process of constraint programming, and their fitness is determined by the quality of solutions obtained for training instances.

Enhancing Constraint Programming via Supervised Learning for Job Shop Scheduling

no code implementations26 Nov 2022 Yuan Sun, Su Nguyen, Dhananjay Thiruvady, XiaoDong Li, Andreas T. Ernst, Uwe Aickelin

Finally, we demonstrate that hybridising the machine learning-based variable ordering methods with traditional domain-based methods is beneficial.

Adaptive Population-based Simulated Annealing for Uncertain Resource Constrained Job Scheduling

no code implementations31 Oct 2022 Dhananjay Thiruvady, Su Nguyen, Yuan Sun, Fatemeh Shiri, Nayyar Zaidi, XiaoDong Li

While a number of optimisation methods have been proposed to tackle the deterministic problem, the uncertainty associated with resource availability, an inevitable challenge in mining operations, has received less attention.

An Efficient Merge Search Matheuristic for Maximising the Net Present Value of Project Schedules

no code implementations20 Oct 2022 Dhananjay R. Thiruvady, Su Nguyen, Christian Blum, Andreas T. Ernst

This paper presents a novel matheuristic framework designed for resource constrained project scheduling, Merge search, which is a variable partitioning and merging mechanism to formulate restricted mixed integer programs with the aim of improving an existing pool of solutions.
