Adding color: Visualization of energy landscapes in spin glasses
Katja Biswas, Helmut G. Katzgraber
Disconnectivity graphs are used to visualize the minima and the lowest energy barriers between the minima of complex systems. They give an easy and intuitive understanding of the u…
The Wishart planted ensemble: A tunably-rugged pairwise Ising model with a first-order phase transition
Firas Hamze, Jack Raymond, Christopher A. Pattison +2
We propose the Wishart planted ensemble, a class of zero-field Ising models with tunable algorithmic hardness and specifiable (or planted) ground state. The problem class arises fr…
A thermally-driven differential mutation approach for the structural optimization of large atomic systems
Katja Biswas
A computational method is presented which is capable to obtain low lying energy structures of topological amorphous systems. The method merges a differential mutation genetic algor…
An iterative aggregation and disaggregation approach to the calculation of steady-state distributions of continuous processes
Katja Biswas
A mapping of the process on a continuous configuration space to the symbolic representation of the motion on a discrete state space will be combined with an iterative aggregation a…
