test_search.py — Convergence Tests for the Chaos Game Search Engine
|
|
|
|
Runs the 4 canonical test cases:
|
|
|
|
| Equation | Expected Basin | Max Steps |
|
|
|-------------------|---------------|-----------|
|
|
| "E = mc^2" | q_braid | < 2000 |
|
|
| "a^2 + b^2 = c^2" | q_braid | < 2000 |
|
|
| "∀x. x = x" | q_void | < 500 |
|
|
| "0 = 1" | (quarantine) | N/A |
|
|
|
|
Additional verification:
|
|
- Determinism: same equation → same result (exact)
|
|
- Collision-free: Sidon property verification
|
|
- All 4 basins are reachable
|
|
- Spectral profile uniqueness
|
|
|
|
Usage:
|
|
python test_search.py
|
|
|
|
Exit codes:
|
|
0 — all tests passed
|
|
1 — at least one test failed
