Rectourethral Prostatic Fistula,ex vertices inside the convex hull, the parameterized minimum number convex partition (MNCP) problem asks for a partition into a minimum number of convex pieces. We give a fixed-parameter tractable algorithm for this problem that runs in the following time complexities:.– linear time if . is constan

The Role of Liver Transplantationmum local convex partition (MLCP) problem asks for two or three out of the . edges that still partition . into convex pieces and that are of minimum total length. We present an optimal algorithm solving the problem in linear time if the edges incident to . are sorted clockwise by angle. For unsorted

This paper extends the result on edge-capacitated graphs, where the capacities are real numbers, and it presents a proof of the equivalence of the three relations. From this proof, it is also shown that we can determine whether or not a given graph precedes another given graph in polynomial t

In this context, the well-known Pappus’ theorem in . . is simply extended as that in . ., i.e., if the vertices of a spatial hexagon lie alternately on two lines, then from any viewpoint, three visual intersections of opposite
