Consider the following bipartite graph G. MA (a) Apply the maximum matching algorithm to G with initial matching M = {X2Y1, X3Y3, X5Y4, Xsys} to find a maximum matching.? Key in the following info in the required formats: When 1st breakthrough is reached: The label of vertices in X bipartition is ? (Eg: (**.y 1,N,y4,N) where "N" means no-label for the vertex) The label of vertices in?Y bipartition is ? (Eg: (x4,N,x2,N,x4,x1) where "N" means no-label.) When 2nd breakthrough or 'STOP' is reached: The label of vertices in X bipartition is The label of vertices in Y bipartition is The maximum matching is: (Key-in the edges in alphabetical order, Eg. {x1y1, x2y5...., x6y3}.) (b) is your maximum matching a perfect matching?? ? ("Y" for Yes, "N" for No) (c) Is it true that a perfect matching is always a maximum matching? ("Y" for Yes, "N" for No) (d) Is it true that a maximum matching is always a perfect matching? ?("Y" for Yes, "N" for No) Consider the following bipartite graph G.
