Efficient Local and Tabu Search Strategies for Large-Scale Quadratic Integer Programming
Haibo Wang, Bahram Alidaee
This study investigates the area of general quadratic integer programming (QIP), encompassing both unconstrained (UQIP) and constrained (CQIP) variants. These NP-hard problems have…
Hybrid Heuristic Algorithms for Adiabatic Quantum Machine Learning Models
Bahram Alidaee, Haibo Wang, Lutfu Sua +1
Numerous established machine learning models and various neural network architectures can be restructured as Quadratic Unconstrained Binary Optimization (QUBO) problems. A signific…
A Unified Framework for Integer Programming Formulation of Graph Matching Problems
Bahram Alidaee, Haibo Wang, Hugh Sloan
Graph theory has been a powerful tool in solving difficult and complex problems arising in all disciplines. In particular, graph matching is a classical problem in pattern analysis…
Will Southeast Asia be the next global manufacturing hub? A multiway cointegration, causality, and dynamic connectedness analyses on factors influencing offshore decisions
Haibo Wang, Lutfu S. Sua, Jun Huang +2
The COVID-19 pandemic has compelled multinational corporations to diversify their global supply chain risk and to relocate their factories to Southeast Asian countries beyond China…
Enhancing supply chain security with automated machine learning
Haibo Wang, Lutfu S. Sua, Bahram Alidaee
The increasing scale and complexity of global supply chains have led to new challenges spanning various fields, such as supply chain disruptions due to long waiting lines at the po…
Multilevel Facility Location Optimization: A Novel Integer Programming Formulation and Approaches to Heuristic Solutions
Bahram Alidaee, Haibo Wang
We attack the 4-level facility location problem (4L-FLP), a critical component in supply chains. Foundational tasks here involve selecting markets, plants, warehouses, and distribu…
