Determining policy for a system dynamics model using reinforcement learning
System dynamics allows managers and policy makers to analyze problems with non-linear feedback structures and thus counter-intuitive behavior. A main tool of system dynamics is to build a computational model of a system and analyze it to determine suitable policies to move the system to a desired …

A Multi-Region Multi-Timescale Burning Plasma Dynamics Model for Tokamaks
… tokamaks brings forth demands for burning plasma dynamics research. The deuterium-tritium fusion generates energetic alpha particles, which first transfer their energy to core electrons. The heated electrons and remaining fusion alpha particles then heat core ions through Coulomb collisions, which …
