Quality-Weighted Vote Aggregator
Software componentCognitionCognition & Memoryarc:QualityWeightedVoteAggregator
A self-consistency aggregator that weights each sampled path's vote by its reasoning-quality score, and can average stated probabilities weighted by quality.
Responsibility. Selects the answer by reasoning-quality-weighted voting across samples.
Also known as: Reasoning-Aware Self-Consistency (RASC) aggregator, Weighted voting
Variant of Self-Consistency Aggregator abstract
When to choose. Choose for medium-to-hard problems with larger sample counts (k≈10-40) or cost-constrained high-stakes deployments where extracting more signal from fewer samples justifies ~5% quality-scoring overhead.

Design guidance
- SHOULD be combined with difficulty-adaptive sample allocation to minimise total samples.
Quantitative guidance
As stated by the sources; verify before use.
- RASC with k=10 matches standard Self-Consistency at k=40 (~70% sample reduction) at ~5% extra tokens per sample (Ch5.3).
- RASC plus adaptive k averages k=6-8 samples for accuracy comparable to k=40, cutting cost 80-85% (Ch5.3).
- Quality weighting raises effective sample efficiency 2-3x at k=15-40 (Ch5.3).
