Detailed Description

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

These constraint do not necessarily belong to the ILP formulation, but have the purpose to strengthen the LP-relaxations in the case of very dense Graphs, by restricting the maximum number of edges that can occur in any optimal solution according to Euler's formula for planar Graphs: |E| <= 3|V|-6
