## 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`
