Pareto Frontier Optimizer
Software componentCognitionCognition & Memoryarc:ParetoFrontierOptimizer
A multi-objective decision component that computes the set of non-dominated (Pareto-optimal) candidate solutions across unweighted objectives instead of a single scalarized optimum.
Responsibility. Identifies the Pareto frontier of non-dominated options for downstream trade-off selection.
Also known as: Multi-objective optimizer, Pareto front computation
Variant of Decision Engine abstract
When to choose. Choose when multiple stakeholders hold diverse or disputed preferences, when trade-offs must be explored before committing, or when objectives are incommensurable and resist a common scale.

Design guidance
- SHOULD present Pareto-optimal alternatives to stakeholders rather than a single weighted optimum when objectives are incommensurable.
- MAY compute Pareto frontiers at design time to validate that acceptable solutions exist, then deploy scalarized utilities for real-time operation.
- SHOULD use evolutionary approximation when exhaustive enumeration of non-dominated solutions is prohibitive.
