SR-DEC Examples

My figure

SR-DEC: Symbolic Regression with Discrete Exterior Calculus primitives.

This repository contains the scripts to reproduce the benchmark problems discussed in the paper Discovering interpretable physical models with symbolic regression and discrete exterior calculus.

Benchmark problems:

  • Poisson equation

My figure

  • Euler's Elastica

My figure

  • Linear Elasticity

My figure

Installation

The dependencies are collected in environment.yml and can be installed, after cloning the repository, using mamba:

$ mamba env create -f environment.yml

Running the benchmarks

For each benchmark, run the corresponding main script (stgp_ + benchmark name), for example for Poisson:

$ python stgp_poisson.py

Check the online documentation of Flex for the meaning of the configuration parameters included in the .yaml files.
