....The width of a partially ordered set is the size of its largest antichain. Orders of small width are a particularly attractive class since several optimization problems, known to be intractable for general orders as can be solved in polynomial time when the input is restricted to this class [3, 27, 26, 10]. It is therefore desirable to have fast recognition algorithms for orders of small width. Since the width of an n element order can be obtained using a max ow computation on a bipartite network with unit capacities there is a O(n 5=2 ) recognition algorithm. For special classes of orders much ....
