# Optimizations of the Social Force Model
## Table of Contents
Summary of optimization attempts. Each optimization has its own details file
under `docs/optimization_<name>.md`. Use `docs/optimization_template.md` as
the starting point for a new entry.
1. [Performance Results](#performance-results)
2. [Baseline](#2-baseline)
3. [Optimization 1](#3-optimization-1)
4. [Optimization 2](#4-optimization-2)
5. [Optimization 3](#5-optimization-3)
6. [Optimization 4](#6-optimization-4)
7. [Optimization 5](#7-optimization-5)
8. [Optimization 6](#8-optimization-6)
9. [Optimization 7](#9-optimization-7)
10. [Optimization 8](#10-optimization-8)
11. [Optimization 9](#11-optimization-9)
To document a new optimization:
```
cp docs/optimization_template.md docs/optimization_<your_name>.md
```
Fill it in, then add a row to the tables below pointing at your file.

## 2. Baseline
**Author**: [Name]
**Description**:
Standard implementation without optimizations.
```cpp
// Paste your code here only the relevant part
```
---
## 3. Optimization 1
**Author**: [Quy Anh] «Elliot» Nguyen
**Description**:
Manually inlined functions, namely `w`, `acceleration_term_dt`, `pedestrian_repulsion_dt`, `obstacle_repulsion_dt`, `norm`, `dot`, and `find_nearest_obstacle_point`, all into `run_simulation`. Got rid of small number checks after verifying they do not affect results. Removed all references to `Vector2d` and rewrote `Pedestrian` into a struct of doubles. Reduced `sqrt()` calls using mathematical properties.
**Relevant Files**: `variant_inlining_1.cpp`, `variant_inlining_2.cpp`, `variant_inlining_3.cpp`, `variant_inlining_4.cpp`, `variant_inlining_5.cpp`, `variant_inlining_6.cpp`, `variant_inlining_7.cpp`, `pedestrian_reduced.hpp`
