Earliest-Plateau Equality

Earliest-Plateau Equality is the strict-left and inclusive-right comparison policy that assigns an equal plateau to its earliest eligible member.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

When highs or lows tie, the first qualifying bar owns the plateau under this convention.

Technical

Strict comparison on the left rejects a later equal candidate; inclusive comparison on the right permits the earliest member to survive.

Scope

Changing inequality direction creates a different valid detector and changes labels.

Examples

  • A reviewer computes Earliest-Plateau Equality on a small deterministic fixture and checks timing, units, and boundary behavior before publication.

Common misconceptions

  • Changing inequality direction creates a different valid detector and changes labels.
