In the published article, the conflict of interest lacked necessary details regarding a previous collaboration between author Pau Loke Show & reviewer Nguyen Thi Dong Phuong. An investigation by the ...

We introduce a method for solving a quadratic unconstrained binary optimization (QUBO) with the two-way one-hot constraints by dividing the QUBO into parts and solving it with an Ising machine. The ...

Current quantum computers can only solve optimization problems of a very limited size. For larger problems, decomposition methods are required in which the original problem is broken down into several ...

Abstract: Isoperimetric graph partitioning, which is also known as the Cheeger cut, is NP-hard in its original form. In the literature, multiple modifications to this problem have been proposed to ...
