%description
A comprehensive toolkit for discovering differential and difference
equations from empirical time series data using symbolic regression. The
package implements a complete workflow from data preprocessing (including
Total Variation Regularized differentiation for noisy economic data),
visual exploration of dynamical structure, and symbolic equation discovery
via genetic algorithms. It leverages a high-performance 'Julia' backend
('SymbolicRegression.jl') to provide industrial-grade robustness,
physics-informed constraints, and rigorous out-of-sample validation.
Designed for economists, physicists, and researchers studying dynamical
systems from observational data.
