Direct comparison of stochastic driven nonlinear dynamical systems for combinatorial optimization
Junpeng Hou, Amin Barzegar, Helmut G. Katzgraber
Combinatorial optimization problems are ubiquitous in industrial applications. However, finding optimal or close-to-optimal solutions can often be extremely hard. Because some of t…
Optimization and benchmarking of the thermal cycling algorithm
Amin Barzegar, Anuj Kankani, Salvatore Mandrà +1
Optimization plays a significant role in many areas of science and technology. Most of the industrial optimization problems have inordinately complex structures that render finding…
Computational Overhead of Locality Reduction in Binary Optimization Problems
Elisabetta Valiante, Maritza Hernandez, Amin Barzegar +1
Recently, there has been considerable interest in solving optimization problems by mapping these onto a binary representation, sparked mostly by the use of quantum annealing machin…
Numerical observation of a glassy phase in the three-dimensional Coulomb glass
Amin Barzegar, Juan Carlos Andersen, Moshe Schechter +1
The existence of an equilibrium glassy phase for charges in a disordered potential with long-range electrostatic interactions has remained controversial for many years. Here we con…
Distribution of interevent avalanche times in disordered and frustrated spin systems
John Ferre, Amin Barzegar, Helmut G. Katzgraber +1
Hysteresis loops and the associated avalanche statistics of spin systems, such as the random-field Ising and Edwards-Anderson spin-glass models, have been extensively studied. A pa…
Optimization of population annealing Monte Carlo for large-scale spin-glass simulations
Amin Barzegar, Christopher Pattison, Wenlong Wang +1
Population annealing Monte Carlo is an efficient sequential algorithm for simulating k-local Boolean Hamiltonians. Because of its structure, the algorithm is inherently parallel an…
