Finding Ground States of Sherrington-Kirkpatrick Spin Glasses with Hierarchical BOA and Genetic Algorithms
Martin Pelikan, Helmut G. Katzgraber, Sigismund Kobe
This study focuses on the problem of finding ground states of random instances of the Sherrington-Kirkpatrick (SK) spin-glass model with Gaussian couplings. While the ground states…
Ground-state energy and frustration of the Sherrington-Kirkpatrick model and related models
S. Kobe
Exact ground states are calculated for the Sherrington-Kirkpatrick (SK) spin-glass containing up to N=90 spins. A ground-state energy per spin …
Time decay of the remanent magnetization in the spin glass model at T=0
J. Klos, S. Kobe
Using the zero-temperature Metropolis dynamics, the time decay of the remanent magnetization in the Edward-Anderson spin glass model with a uniform random distribution of f…
An exact learning algorithm for autoassociative neural networks with binary couplings
G. Milde, S. Kobe
Exact solutions for the learning problem of autoassociative networks with binary couplings are determined by a new method. The use of a branch-and-bound algorithm leads to a substa…
Ernst Ising - physicist and teacher
S. Kobe
The Ising model is one of the standard models in statistical physics. Since 1969 more than 12000 publications appeared using this model. In 1996 Ernst Ising celebrated his 96th bir…
Exact low-energy landscape and relaxation phenomena in ISING spin glasses
T. Klotz, S. Kobe
All ground states and low-lying excitations of a +/- I Ising spin glass model on a cubic 4 x 4 x 4 lattice with periodical boundary conditions were calculated using a method of com…
