Monte Carlo Methods in Practice and Efficiency Enhancements via Parallel Computation
… up Monte Carlo algorithms by running them in parallel computing environments. The compute time of Monte Carlo algorithms is random and can vary depending on the current state of the Markov chain. Other computing-infrastructure related factors, such as competing jobs on the same processor, or …

Computational Studies of Correlated Electrons in One-Dimension
… Monte Carlo method and the use of Quantum Parallel Tempering to improve the quality of the numerical data. For the extended Hubbard model at half-filling, we have confirmed the existence of a recently reported bond-order wave phase for the ground state in a small region of parameter space …

Investigation of Ni-Ceria Nanocatalysts: Improved Computational Methods Towards Hydrogen Production in Aquaprocessing of Heavy Oil
… further investigation of the NPs by mass-scaled parallel-tempering Born-Oppenheimer molecular dynamics (PT-BOMD) resulted in the same global minima (GM) structures found by AL, demonstrating the robustness of our AL search. This AL strategy has shown to be a powerful tool for learning from small …

Unconventional computing platforms and nature-inspired methods for solving hard optimisation problems
… such as the Hopfield-Tank neural networks and parallel tempering, we consider a recent physics-inspired algorithm, namely chaotic amplitude control, and exact commercial solver, Gurobi. For a proper evaluation of physical simulators, we further discuss the importance of detecting easy instances …

Gain-Based Computing for Solving Optimisation Problems
… is compared to the powerful classical heuristic parallel tempering algorithm. We utilise the time-to-solution metric to analyse and compare the expected time to achieve an N-queens solution when each method is implemented on its natural hardware. This allows us to examine the possibility of an …
