We characterize (0,l) linear programming matrices for which a greedy algorithm and its dual solve certain covering and packing problems. Special cases are shortest path and minimum spanning tree algorithms.
This note supplements an earlier paper of this author, in which the concept of a strong k-hypomorphism between two graphs was defined (Thatte, 1990, Section VI). For k = 1, this is just a hypomorphism. Here it is proved that strongly k-hypomorphic graphs and strongly k-edge hypomorphic directed grap
We construct a graph on a planar point set, which captures its shape in the following sense: if a smooth curve is sampled densely enough, the graph on the samples is a polygonalization of the curve, with no extraneous edges. The required sampling density varies with the local feature size on the cur
