In this paper, researchers tackle a bottleneck in policy optimization algorithms that simulates a single trajectory of a dynamical system under a state-dependent policy. The authors propose an iterative algorithm called Picard Iteration to accelerate policy simulation, which assigns tasks to independent processes and updates a cache at the end of each iteration. This scheme is implemented on GPUs, allowing for batched evaluation of the policy across a single trajectory. The researchers prove that their method converges quickly in many supply chain optimization problems and demonstrate practical speedups of 400x on large-scale SCO problems.
Low GrooveSquid.com (original content) Low Difficulty Summary
The Picard Iteration algorithm helps solve a problem in optimizing policies by speeding up simulations of complex systems. By breaking down big tasks into smaller ones and using computers to do lots of calculations at the same time, this method makes it much faster to test different options for managing supply chains or other complex systems.
