# EvaluatorOptimizer

Generate-evaluate-refine loop

Layer: Society · Category: Protocols

## Mechanism

A two-role [Loop](https://mindscape.world/scapes/bootstrap/Loop.md) to [Optimize](https://mindscape.world/scapes/bootstrap/Optimize.md) a solution where a Generator produces output and an Evaluator critiques it, providing structured feedback. The feedback is fed back to the Generator for refinement. [Loop](https://mindscape.world/scapes/bootstrap/Loop.md) continues until the Evaluator approves or max iterations reached. The Evaluator can be the same model with a different [Context](https://mindscape.world/scapes/bootstrap/Context.md), or a separate model. It invokes a [MetaCheck](https://mindscape.world/scapes/bootstrap/MetaCheck.md) to ensure the scoring [Criteria](https://mindscape.world/scapes/bootstrap/Criteria.md) remain consistent across optimization cycles.

## Invariants

- Feedback loop converges
- Optimizer improves score on Evaluator metric

## Preconditions

- Initial solution
- Modification operator
- Scoring function

## Postconditions

- High-quality solution found

## Failure modes

- Evaluation Drift: Evaluator criteria shift across iterations.
- Cosmetic Changes: Generator makes superficial edits that don't address feedback.
- Evaluator Capture: Generator learns to game the evaluator's criteria.

## Signature

- `Optimize(Loop)`
