Cluster-based Message-Passing (CluMP) Optimization for Complex QUBO Problems
Paolo Rissone, Stefan Boettcher, Alfonso Amendola +2
Quadratic Unconstrained Boolean Optimization (QUBO) problems are widespread in both industrial applications and scientific studies. A QUBO problem corresponds to the optimization o…
Ground States of the Mean-Field Spin Glass with 3-Spin Couplings
Stefan Boettcher, Ginger E. Lau
We use heuristic optimization methods in extensive computations to determine with low systematic error ground state configurations of the mean-field -spin glass model with …
Hysteretic response to different modes of ramping an external field in sparse and dense Ising spin glasses
Mahajabin Rahman, Stefan Boettcher
We consider the hysteretic behavior of Ising spin glasses at for various modes of driving. Previous studies mostly focused on an infinitely slow speed by which the…
Physics of the Edwards-Anderson Spin Glass in Dimensions from Heuristic Ground State Optimization
Stefan Boettcher
We present a collection of simulations of the Edwards-Anderson lattice spin glass at to elucidate the nature of low-energy excitations over a range of dimensions that reach f…
