Given a multigraph, please choose one of the following C++ files according to the existence of an edge from P_0 to P_1 and/or an edge from P_(n-1) to P_n, where "P_i" denotes the fixed point with "i" negative isotropy weights.

Then insert the expression in CForm (given by Part II of MinimalIW.nb) of the corresponding determinant and follow the enclosed instructions.

To be used when the multigraph has an edge from P0 to P1 but no edge from P(n-1) to Pn.
To be used when the multigraph has an edge from P(n-1) to Pn but no edge from P0 to P1.
To be used when the multigraph has an edge from P0 to P1 and an edge from P(n-1) to Pn.
To be used when the multigraph has none of the above edges.
