Project description and instructions
This repository contains code illustrating two approaches to automate gradient computation for collective variables in PLUMED. The two approaches are used to implement the example colvars CURVATURE_CODEGEN and CURVATURE_AUTODIFF, which compute the radius of curvature given three atoms, and CURVATURE_MULTICOLVAR_CODEGEN, given a polymer. The code is found in submodules named src/curvature_codegen (code generation approach from symbolic expressions by SymPy) and src/curvature_autodiff (code differentiation approach with the Stan Math library). Example files with regression tests are provided in the directories regtest/curvature_codegen and regtest/curvature_autodiff respectively.
