Definition
Plain language
The set of options where none can be made better at one thing without getting worse at another.
As stated in the literature
The set of non-dominated candidates across multiple objectives; used in optimize-anything as the survival mechanism for diverse specialists across per-example or per-subscore performance dimensions.
Also called: Pareto front, Pareto frontiers
Why it matters: Keeping the frontier rather than a single winner preserves diverse solutions and prevents premature convergence in search.
For example, when packing circles, one design might be best for total area while another is best for symmetry, and both sit on the Pareto frontier.

“The cleanest way to see the whole thing is the Pareto frontier — that menu of best tradeoffs.”Episode 179 — How DeepSeek Made One User Faster Without Slowing Down the Crowd
