ropelength In physical knot theory, each realization of a link or knot has an associated ropelength. Intuitively this is the minimal length of an ideally flexible rope that is needed to tie a given link, or knot. Knots and links that minimize ropelength are called ideal knots and ideal links respectively. == Definition == The ropelength of a knot curve ''C'' is defined as the ratio , where Len(''C'') is the length of ''C'' and τ(''C'') is the thickness of the link defined by ''C''.
