Novelty-Based Generation of Continuous Landscapes with Diverse Local Optima Networks
Kippei Mizuta, Shoichiro Tanaka, Shuhei Tanaka +1
Local Optima Networks (LONs) represent the global structure of search spaces as graphs, but their construction requires iterative execution of a search algorithm to find local opti…

Fair sampling with temperature-targeted QAOA based on quantum-classical correspondence theory
Tetsuro Abe, Shu Tanaka
In combinatorial optimization problems with degenerate ground states, fair sampling of degenerate solutions is essential. However, the quantum approximate optimization algorithm (Q…

Structural Comparison of Error Mitigation Methods for Ising Machines: Penalty-Spin Model versus Stacked Model
Tetsuro Abe, Kanta Hino, Shu Tanaka
Error-mitigation methods for Ising machines are reexamined not merely as noise-suppression techniques but as a structural design problem of replica-coupled Ising models. Using simu…
