Performance analysis of classical adiabatic annealing on Ising machines

Jacob Lamers, Guy Verschaffelt, Guy Van der Sande

Ising machines are a promising approach to solve combinatorial optimization problems. They map these problems onto the Ising model and search for low-energy configurations. However, navigating the rugged energy landscapes of these systems remains difficult. To improve this navigation, classical adiabatic annealing …

Beyond Gradient Descent: Adam for Analog Ising Machines

Stijn Van Vooren, Guy Van der Sande, Guy Verschaffelt

As Moore's law reaches its limits, Ising machines offer a promising alternative computing approach for difficult optimization problems. However, many analog, time-continuous Ising machines rely on gradient-descent-like dynamics to find solutions, which can limit speed and robustness. We investigate whether momentum and …

Reducing hyperparameter sensitivity in measurement-feedback based Ising machines

Toon Sevenants, Guy Van der Sande, Guy Verschaffelt

Analog Ising machines have been proposed as heuristic hardware solvers for combinatorial optimization problems, with the potential to outperform conventional approaches, provided that their hyperparameters are carefully tuned. Their temporal evolution is often described using time-continuous dynamics. However, most experimental implementations rely …

Predicting the optimal noise strength for solving optimization problems with analog Ising machines

Leen Mys, Guy Verschaffelt, Guy Van der Sande

Analog Ising machines are dedicated hardware solvers designed to solve NP hard optimization problems. However, the global optimum is often not found as the system gets stuck in local minima. While several strategies exist to increase the chance of escaping local minima, …

Incorporating external fields in analog Ising machines

Robbe De Prins, Jacob Lamers, Peter Bienstman, Guy Van der Sande et autres

Ising machines are specialized devices designed to efficiently solve combinatorial optimization problems. They consist of artificial spins that evolve towards a low-energy configuration representing a problem’s solution. Most realistic problems require both spin-spin couplings and external fields. In Ising machines with analog …
