Finding all characteristic curves of nonlinear resistive circuits using the dual simplex method
K. Yamamura, Takayoshi Kumakura · 2002
An efficient algorithm is proposed for finding all characteristic curves of nonlinear circuits. This algorithm is based on a simple test for nonexistence of a characteristic curve in a region X. In this test, the dual simplex method is applied to a linear programming problem whose feasible region contains all characteristic curves in X. This test is not only powerful but also efficient and requires only a few pivotings per region.
