Comparative Study of Potts Machine Dynamics and Performance for Max-k-Cut
Bjarke Almer Frederiksen, Robbe De Prins, Peter Bienstman
Combinatorial optimization problems in logistics, finance, energy, and scheduling routinely involve multi-state decision variables. Ising machines (IMs) require binary expansions (…

A More Convex Ising Formulation of Max-3-Cut Using Higher-Order Spin Interactions
Robbe De Prins, Guy Van der Sande, Peter Bienstman +1
Many combinatorial optimization problems (COPs) are naturally expressed using variables that take on more than two discrete values. To solve such problems using Ising machines (IMs…

How to Incorporate Higher-order Interactions in Analog Ising Machines
Robbe De Prins, Guy Van der Sande, Peter Bienstman +1
Ising machines (IMs) are specialized devices designed to efficiently solve combinatorial optimization problems. Among such problems, Boolean Satisfiability (SAT) is particularly re…
