What this part means

A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.

Its job in the formula

A raised mark can be a power or an index. Its position and the surrounding notation determine which.

The passage around this formula

The shared structural fact underneath both techniques, and the reason they are described here as one machine rather than two, is what a search process buys once it is automated rather than performed by hand. A single human red-teamer trying prompt variations by hand might realistically test dozens of candidates against a target in a working day. An automated pipeline built on either GCG- or PAIR-style search can attempt thousands of candidates against a running target in the same interval, entirely unattended. If a given search strategy succeeds against a defended target with independent per-attempt probability p , the probability that at least one of k automated attempts succeeds is…
