Nonlinear resistive networks, which can be characterized by the equation

, where

is a continuous piecewise linear mapping of

into itself, are discussed.

is a point in

and represents a set of chosen network variables and

is an arbitrary point in

and represents the input to the network. New theorems on the existence of solutions together with a convergent method for obtaining at least one of the solutions are given. Also dealt with is an efficient computational algorithm which is especially suited for analysis of large piecewise-linear networks. The effectiveness of the method in terms of the amount of computation and data handling and storage is demonstrated.
