Ising-Machine-Assisted Large Neighborhood Search with Flexibly Tunable Subproblem Size

Koshiro Fujimoto, Masashi Yamashita, Shu Tanaka

Ising machines are heuristic solvers for combinatorial optimization, but their solution quality can degrade when large-scale constrained problems are solved directly. Ising-machine…

Geometric Characteristics of Subproblems in Ising-Machine-Assisted Large Neighborhood Search

Masashi Yamashita, Shu Tanaka

Large-scale quadratic unconstrained binary optimization (QUBO) formulations of constrained combinatorial optimization problems often exceed the input-size limit of present Ising ma…

Effectiveness of Binary Autoencoders for QUBO-Based Optimization Problems

Tetsuro Abe, Masashi Yamashita, Shu Tanaka

In black-box combinatorial optimization, objective evaluations are often expensive, so high quality solutions must be found under a limited budget. Factorization machine with quant…

Annealing-Assisted Column Generation for Inequality-Constrained Combinatorial Optimization Problems

Hiroshi Kanai, Masashi Yamashita, Kotaro Tanahashi +1

Ising machines are expected to solve combinatorial optimization problems faster than the existing integer programming solvers. These problems, particularly those encountered in pra…
