Equation 15 · Part 11 · The Hardest Unsolved Problems in AI Agent Evaluation and Reliability
Ending index or upper bound: n
What this part means
This label says where the repeated addition, multiplication, or accumulation stops. It sets the last term or end of the range.
Its job in the formula
n appears in the bound of this sum. The bound states where the repeated operation starts, ends, or which values it includes.

The passage around this formula
and contrast it with a severity-weighted version, . where scales each failure by how costly it actually was. Two agents can share an identical of, say, ninety-five percent, while one of them fails harmlessly - an unhelpful but reversible answer - and the other fails catastrophically - an irreversible transaction, a deleted repository, a wrong medical dosage recommendation - on that same five percent. No standard agent benchmark publishes R , because assigning a defensible requires a judgment about real-world consequence that a replayable, sandboxed task suite is not built to carry, and because the tasks that would carry the highest weights are, not…

Σ adds a collection of terms. Π multiplies them. The lower and upper labels tell you which terms belong to the collection.
