Hysteresis in Combinatorial Optimization Problems

Proceedings of the International Florida Artificial Intelligence Research Society Conference, 2021
Hysteresis is a physical phenomenon reflected in macroscopic observables of materials that are subjected to external perturbations. For example, magnetic hysteresis is observed in ferromagnetic metals such as iron, nickel and cobalt in the presence of a ...
