Questions tagged [metric]

Quoting Wikipedia:

In mathematics, a metric or distance function is a function that defines a distance between each pair of elements of a set. A set with a metric is called a metric space. A metric induces a topology on a set, but not all topologies can be generated by a metric. A topological space whose topology can be described by a metric is called metrizable.

is used in any kind of question related to compute, define, choose a metric, and such.
