In mathematics, Chebyshev distance (or Tchebychev distance ), maximum metric, or L metric is a metric defined on a vector space where the distance between two vectors is the greatest of their differences along any coordinate dimension. It is named ...

In linear algebra, functional analysis and related areas of mathematics, a norm is a function that assigns a strictly positive length or size to each vector in a vector space save possibly for the zero vector, which is assigned a length of zero. A ...

In mathematics, the Euclidean distance or Euclidean metric is the ordinary (i.e straight line) distance between two points in Euclidean space. With this distance, Euclidean space becomes a metric space. The associated norm is called the Euclidean ...
