NEXT: HIGH-VALUE TARGETS
1. TASK 034 — ONNX BUILD IN PROGRESS (267/267 solved!)
Rule: Diagonal trail of 2x2 block. Direction from 2-markers. 9×9 grid. Base: 87 nodes, 2847 params, score 13.42 Status: Solver 267/267. ONNX works for 1-marker cases (85/267). Blocker: Multi-directional (2+ markers) cases fail in ONNX due to Sign(0)=0 when block center == 2-cell mean. Need to handle:
- 2 markers → bidirectional (opposite diagonals)
- 3 markers → need to detect the MISSING corner of the bounding box as direction Fix needed: When Sign gives 0 (centroids coincide), use individual 2-cell positions to determine unique diagonal directions, then trail in ALL detected directions. Potential gain: +1-2 pts if ONNX beats base
2. TASK 076 — SOLVER COMPLETE (266/266) but ONNX BLOCKED
Rule: Template rotation + decoration placement using centroid + 2-marker + BFS
Base: 10.34 (949KB file)
Potential: +5-7 pts
Blocker: Requires 8-connected CC detection + BFS. Objects can be adjacent (distance 0).
Simple separation won't work. Need ~100+ extra nodes for iterative CC propagation.
File: task076_solver_266.py
3. TASK 219 — SOLVER AT 255/265, needs 265 for ONNX
Rule: Template pattern extension with alignment + periodicity
Base: 8.42 (87KB file)
Potential: +6 pts
Blocker: 10 "merged row" failures where group rows contain columns from multiple template rows
File: task219_solver_255.py
4. TASK 366 — NOT STARTED (highest potential +8-10 pts)
Base 7.08, file 1.3MB, variable grid. Object placement by dot-pattern matching. Extremely complex — needs backtracking.
5. TASK 157 — NOT CRACKED
10×15 grid. Column shift rule unclear.
WORKFLOW PER TASK
1. Load task JSON, look at 2-3 train examples
2. Use ARC-DSL primitives (michaelhodel-arc-dsl.txt) to identify the rule
3. Write Python solver, verify 265+/265 accuracy on ALL examples
4. Build ONNX using OnnxBuilder (slice-first pattern)
5. Run onnxsim
6. **PROFILE** score with score_model.py — NEVER use static estimates
7. **PROFILE** base model score too
8. ONLY if my_score > base_score: upload to optimized/
PROVEN FAILURES (do NOT retry)
| Approach | Result |
|---|---|
| Task 398 ONNX | 268/268 correct but scores 10.3 vs base 13.7 (base too compact: 770 params) |
| Float16 conversion | Cast overhead cancels savings |
| onnx-neural-compressor quantization | Introduces DynamicQuantizeLinear/MatMulInteger → scorer returns None |
| Task 363 heuristics (×7) | 264/265 max, unknown tiebreaker |
| Tasks needing CC detection (101, 233, 191, 044, 077, 182) | Can't express in ONNX efficiently |
| onnxsim on base models | Only 3 out of 400 improved (209, 367, 323) — already done |
| Task 314 hand-craft ONNX | 266/266 correct BUT scored 14.46 vs base 15.62 = WORSE |
| Targeting tasks with base params < 1000 | Base already too compact to beat |
DO NOT TOUCH
- Tasks with base score > 14 and small grids (flips, rotations, color swaps)
- Tasks 020, 037, 040, 053, 077, 098, 100, 291, 307, 330
- Task 057, 384 (removed — score WORSE than base)
- Task 314 (266/266 correct but ONNX scores 14.46 vs base 15.62 = WORSE)
- Task 398 (268/268 correct but ONNX scores 10.3 vs base 13.7 = WORSE)
