Extending Sample Persistence Variable Reduction for Constrained Combinatorial Optimization Problems
Shunta Ide, Shuta Kikuchi, Shu Tanaka
Constrained combinatorial optimization problems (CCOPs) are challenging to solve due to the exponential growth of the solution space. When tackled with Ising machines, constraints…
