Two papers are accepted at IEEE High-Performance and Extreme Computing

We are happy to announce that two of our papers have been accepted at the IEEE High-performance and Extreme Computing Conference (HPEC 2023). 

"Hybrid Quantum-Classical Multilevel Approach for Maximum Cuts on Graphs" by Anthony Angone, Xiaoyuan Liu, Ruslan Shaydulin, and Ilya Safro. 

This paper is focusing on the Max-Cut problem. The study introduces a scalable hybrid multilevel approach to solve large instances of Max-Cut using both classical solvers and the quantum approximate optimization algorithm (QAOA). The results showcase the excellent performance of both classical and hybrid quantum-classical methods. 

The solver is publicly available at https://github.com/angone/MLMax-cut. 

Congratulations to the lead student and first author, Anthony Angone! 

"Decomposition Based Refinement for the Network Interdiction Problem" by Krish Matta, Xiaoyuan Liu, and Ilya Safro. 

This paper introduces a novel algorithm for the shortest path network interdiction problem. By decomposing the problem into sub-problems, the method efficiently utilizes Ising Processing Units alongside classical solvers. The results demonstrate comparable quality to existing exact solvers and also highlight a significant reduction in computational time for large-scale instances. 

The source code and experimental results can be accessed at https://github.com/krishxmatta/network-interdiction. 

A special shout-out to the lead student and first author, Krish Matta. A significant portion of his paper was accomplished during his high school years! Once again, congratulations to Anthony and Krish for their outstanding work and contributions to the field. We look forward to presenting these papers at HPEC 2023!
