Abstract
Braids can be represented as two-dimensional diagrams showing the crossings of strings or as words over the generators of a braid group. A minimal braid is one with the fewest crossings (or the shortest words) among all possible representations topologically equivalent to that braid. The main result of this paper is that the set of minimal braids is co-NP-complete.
