  dual graph
We present a new rule based method on dual graph contraction for transforming the run graph and its dual into MLPP graphs.
      
Concentrating strictly on topology, it turns out that the pseudo-dual graph is conceptually cleaner and more efficient in route planning than alternative, currently used ways to deal with turn costs.
      
The pseudo-dual graph is defined here in a new way, it is systematically investigated, and some practical applications are shown.
      
Turn costs can be represented by a pseudo-dual graph in a way that shortest path algorithms run without modifications.
      
Our computational experiments show that the performance of the proposed method is better than that of the dual graph approach, both in terms of computing time and memory requirements.

In this paper the reverse tranformation is derivcd from the reciprocity theorem. The transfer functions of the generalized inverse and the reverse of a given network are the same with different network structures. The reverse transformation of the dual graph of a given network testifies and extends the transition rules proposed in the reference. The transposition with reciprocal is such a transformation that the complex variable s in the original transfer function is replaced by 1/s, It extends the corresponding result of the RC: CR transformation presented in the reference into the RLC networks.
