Quasi-exact ground-state algorithm for the random-field Potts model
Manoj Kumar, Martin Weigel
The use of combinatorial optimization algorithms has contributed substantially to the major progress that has occurred in recent years in the understanding of the physics of disord…

On the comparison of optimization algorithms for the random-field Potts model
Manoj Kumar, Martin Weigel
For many systems with quenched disorder the study of ground states can crucially contribute to a thorough understanding of the physics at play, be it for the critical behavior if t…

Approximate ground states of the random-field Potts model from graph cuts
Manoj Kumar, Ravinder Kumar, Martin Weigel +3
While the ground-state problem for the random-field Ising model is polynomial, and can be solved using a number of well-known algorithms for maximum flow or graph cut, the analogue…
