I'm currently using GDI+ to draw a line graph, and using Graphics.DrawCurve to smooth out the line. The problem is that the curve doesn't always match the points I feed it, and that makes the curve grow out of the graph frame in some points, as seen below(red is Graphics.DrawLines,...

In the first steps, my program adds edges to a given input graph so that it becomes an undirected graph and every vertex chooses a random partition. (This partition-integer is stored in the VertexValue) At the end of this...

Question :- removal of an edge from a given tree T will result in the formation of two separate trees, T1 and T2. Each vertex of the tree T is assigned a positive integer. Your task is to remove an edge, such that the Tree_diff of the resultant trees is...
