# Optimization: Baseline

- **Author**: TBD
- **Predecessor**: N/A (initial reference)
- **File(s)**: variants/variant_baseline.cpp
- **Status**: reference

## What this changes

This is the unoptimized reference implementation of the social force model.
Every other optimization is measured relative to it. See the source file for
the full implementation; key functions are `w()`, `acceleration_term_dt()`,
`pedestrian_repulsion_dt()`, `obstacle_repulsion_dt()`, and `run_simulation()`.
