Detailed Description

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

If some cluster has no connection to some other cluster, the optimal solution might insert a new connection-edge between theese two clusters, to obtain connectivity. Since the objective function minimizes the number of new connection-edges, at most one new egde will be inserted between two clusters that are not connected. This behaviour of the LP-solution is guaranteed from the beginning, by creating an initial constraint for each pair of non-connected clusters, which is implemented by this constraint class.
