  The circuit-theoretic origins of maximal monotonicity are revisited using
modern optimization algorithms for maximal monotone operators. We present an
algorithm for computing the periodic behavior of an interconnection of maximal
monotone systems using a fixed point iteration. The fixed point iteration may
be split according to the interconnection structure of the system. In this
preliminary work, the approach is demonstrated on port interconnections of
maximal monotone resistors and LTI capacitors and inductors.
