See the first 50 failing inputs before shrinking.
Performance
| Metric | Min | Max | Median | Mean | 95% CI |
|---|---|---|---|---|---|
| Evaluations | 63.0 | 266.0 | 122.0 | 124.5 | 123.3–125.6 |
| Reduction time (ms) | 0.91 | 6.95 | 1.62 | 1.67 | 1.65–1.69 |
| Iterations to failure | 5.0 | 23.0 | 7.0 | 7.5 | 7.3–7.6 |
Reproduction
From the exhaust/src folder, run the following command:
swift run ExhaustRunner --challenge bound5 --iterations 1000
The reduction time reflects running on an M4 Max running macOS 26.4. This is an unoptimised debug build, mirroring the experience of using Exhaust inside a swift test target rather than a best-case release benchmark.
