• actn Simple Action Minimizer

Based on the concept of "Action" defined on "trajectories". Action and Lagragian are concepts defined by Joseph-Louis Lagrange that are able to describe the whole classical mechanics.

This script finds a tajectory that minimises the Lagrange-ian Action. It uses random local search (some local Monte Carlo) in space of trajectories.

Left: Trajectories under minimization of A=∫L. Right: A(τ), Action across epocs (τ), and mean rate of decrease of A(τ). Decreases of A of successful steps (mutations).
