ArgMaxUnique(f(x), x, P(x)) represents the unique point r
satisfying P(r)
such that f(r)=P(x)maxf(x). This operation is only defined if such a unique point exists.
The argument x to this operator defines a locally bound variable. The corresponding predicate P(x)
must define the domain of x
unambiguously; that is, it must include a statement such as x∈S
where S
is a known set. More generally, x can be a collection of variables (x,y,…)
all of which become locally bound, with a corresponding predicate P(x,y,…).
Definitions:
| Fungrim symbol | Notation | Short description |
|---|---|---|
| ArgMaxUnique | P(x)argmax*f(x) | Unique location of maximum value |
| Maximum | P(x)maxf(x) | Maximum value of a set or function |
