Description

1.1 INTRODUCTION

Distance is a numerical description of how far apart objects are. In physics or
everyday usage, distance may refer to a physical length, or estimation based on
other criteria (e.g. &quot;two counties over&quot;). In most cases, &quot;distance from A to B&quot; is
interchangeable with &quot;distance from B to A&quot;. In mathematics, a distance function
or metric is a generalization of the concept of physical distance. A metric is a
function that behaves according to a specific set of rules, and is a way of
describing what it means for elements of some space to be &quot;close to&quot; or &quot;far away
from&quot; each other.
