Perfect matching polytope ppm, Data Structure & Algorithms

Assignment Help:

Let G=(V,E) be a graph for which all nodes have degree 5 and where G is 5-edge is connected.

a) Show that the vector x which is indexed by the edges E and for which xe = 1/5 for all e in E is in the Perfect Matching Polytope PPM.

b) Use your result in a) to show that G must have a perfect matching.

c)  Show that b) may not be true if G is only 1-edge connected (but still has degree 5 everywhere) by giving an example of such a graph G which has no perfect matching.
