# SymClaw Benchmarks

Criterion-based benchmarks for the SymClaw symbolic math engine.

## Running

```bash
cargo bench -p symclaw-benchmarks
```

Run a specific group:

```bash
cargo bench -p symclaw-benchmarks -- parsing
cargo bench -p symclaw-benchmarks -- differentiation
```

## Benchmark Groups

| Group | What it measures |
|---|---|
| **parsing** | Expression parsing (simple → complex) |
| **simplification** | Identity removal, constant folding, like-term combination, e-graph |
| **differentiation** | Polynomial, trig, chain rule depth, higher-order (5th derivative) |
| **integration** | Power rule, trig, integration by parts |
| **solving** | Linear, quadratic, cubic equation solving |
| **series** | Maclaurin and Taylor series expansion |
| **egraph** | E-graph simplification (identities, trig, distribution) |
| **latex** | LaTeX rendering |

## Comparing Across Runs

Criterion automatically compares against the previous run and reports percentage changes. HTML reports are saved to:

```
target/criterion/<group>/<benchmark>/report/index.html
```

To save a baseline for later comparison:

```bash
cargo bench -p symclaw-benchmarks -- --save-baseline my_baseline
cargo bench -p symclaw-benchmarks -- --baseline my_baseline
```
