*A [[multistate_character|multistate character]] of which the [[order]] has been determined.  Transformation between any two [[adjacent]] states costs the same number of steps (usually one, see [[direction]]), but transformation between two [[non-adjacent_character|non-adjacent]] states costs the sum of the steps betweentheir implied adjacent states.  For example, in the [[ordered character]], 0 <-> 1 <-> 2, the transformations 0 <-> 1 and 1 <-> 2 each cost the same number of steps but the transformation 0 <-> 2 costs twice as many (i.e. transformation proceeds as if via state 1).  [[Wagner optimization]] uses [[ordered characters]].  Cf. [[unordered]].
