Detailed Description

implementation of initial cut-constraint class for the Branch&Cut algorithm for the Maximum C-Planar SubGraph problem.

A feasible ILP solution has to imply a completely connected, planar Sub-Clustergraph. For each cluster that is not connected, additional connection edges have to be inserted between the chunks of the cluster, to obtain c-connectivity. Thus, initial constraints are added that guarantee initial c-connectivity, if the number of chunks is at most 3. If some cluster consists of more than 3 chunks, additional constraints have to be separated during the optimization.
