Metastate analysis of the ground states of two-dimensional Ising spin glasses
A. K. Hartmann, A. P. Young
Using an efficient polynomial-time ground state algorithm we investigate the Ising spin glass state at zero temperature in two dimensions. For large sizes, we show that the spin st…
Energy landscapes of some matching-problem ensembles
Till Kahlke, Alexander K. Hartmann
The maximum-weight matching problem and the behavior of its energy landscape is numerically investigated. We apply a perturbation method adapted from the analysis of spin glasses.…
Simulated annealing, optimization, searching for ground states
Sergio Caracciolo, Alexander K. Hartmann, Scott Kirkpatrick +1
The chapter starts with a historical summary of first attempts to optimize the spin glass Hamiltonian, comparing it to recent results on searching largest cliques in random graphs.…
