| src/reasoning_benchmark.py | |
| Multi-Step Reasoning Token Complexity Benchmark for Q-TensorFormer. | |
| Evaluates token-by-token informational complexity across real-world problem sets: | |
| - Mathematical Multi-Step Derivation (GSM8K style) | |
| - Algorithmic Code Synthesis & Control Flow | |
| - Symbolic Logic & Deductive Querying | |
| Scientific Objective: | |
| Demonstrates that complex reasoning tokens (mathematical operators, variable bindings, | |
| and logic deductions) dynamically trigger high-rank representations (r in {8, 16}), | |
| while syntax and filler tokens drop to edge ranks (r in {1, 2}), slashing total memory | |
| traffic by over 70% while preserving solution fidelity. | |
