Pareto Frontiers

Abstraction: Multi-objective optimality boundary identifying non-dominated algorithm trade-offs

Key points:

A Pareto frontier contains all solutions where no other solution is strictly better in every dimension simultaneously
A solution not on the Pareto frontier is dominated — another option exists that is at least as good in all ways and strictly better in at least one
Pareto fronts extend to any number of dimensions (speed, accuracy, cost, implementation time, etc.)
The frontier defines the set of solutions that can be rationally argued for; off-frontier solutions have no defensible justification
Useful in CS and philosophy for understanding what "optimal" means when multiple competing criteria exist
