Umbrella Reinforcement Learning -- computationally efficient tool for hard non-linear problems
Egor E. Nuzhin, Nikolai V. Brilliantov
We report a novel, computationally efficient approach for solving hard nonlinear problems of reinforcement learning (RL). Here we combine umbrella sampling, from computational phys…
Supercluster states and phase transitions in aggregation-fragmentation processes
Wendy Otieno, Nikolai V. Brilliantov, P. L. Krapivsky
We study the evolution of aggregates triggered by collisions with monomers that either lead to the attachment of monomers or the break-up of aggregates into constituting monomers.…
Exact solutions of temperature-dependent Smoluchowski equations
Alexander Osinsky, Nikolay Brilliantov
We report a number of exact solutions for temperature-dependent Smoluchowski equations. These equations quantify the ballistic agglomeration, where the evolution of densities of ag…
The velocity dependence of dry sliding friction at the nano-scale
Rasoul Kheiri, Alexey A Tsukanov, Nikolai V Brilliantov
We performed molecular dynamics (MD) experiments to explore dry sliding friction at the nanoscale. We used the setup comprised of a spherical particle built up of 32,000 aluminium…
Aggregation in non-uniform systems with advection and localized source
Rishat R. Zagidullin, Alexander P. Smirnov, Sergey A. Matveev +2
We explore analytically and numerically agglomeration driven by advection and localized source. The system is inhomogeneous in one dimension, viz. along the direction of advection.…
Aggregation kinetics at sedimentation: the impact of particles diffusion
Rishat R. Zagidullin, Alexander P. Smirnov, Sergey A. Matveev +1
We investigate the aggregation kinetics of sedimenting particles theoretically and numerically, using the advection-diffusion equation. Agglomeration, caused by both transport mech…
