Effective optimization using sample persistence: A case study on quantum annealers and various Monte Carlo optimization methods
Hamed Karimi, Gili Rosenberg, Helmut G. Katzgraber
We present and apply a general-purpose, multi-start algorithm for improving the performance of low-energy samplers used for solving optimization problems. The algorithm iteratively…

Building an iterative heuristic solver for a quantum annealer
Gili Rosenberg, Mohammad Vazifeh, Brad Woods +1
A quantum annealer heuristically minimizes quadratic unconstrained binary optimization (QUBO) problems, but is limited by the physical hardware in the size and density of the probl…
