Struct UndirectedTwoCommodityIntegralFlow 

pub struct UndirectedTwoCommodityIntegralFlow { /* private fields */ }

Undirected two-commodity integral flow on a capacitated graph.

For each undirected edge {u, v}, a configuration stores four variables in the graph’s edge order:

• f1(u, v)
• f1(v, u)
• f2(u, v)
• f2(v, u)
