I have not well understood the details of this post but I am very interested in the topic from a user perspective.
I think that you (and the cited paper) are dealing with the possibility of perform a fast resimulation of the circuit after having made a change of a circuit part (trough a partial update of the LU decomposition). I am interested in this capability because I would like to implement a design/optimization strategy for microwave components which is based on a Electromagnetic software I am developing. This software will produce an equivalent circuit that is composed of many subcircuits describing the different parts (subvolumes) of the component. The optimization process typically changes only a few of the subcircuits but the variations are not smooth because of the casualty of some algorithms (like remeshing) and because the equivalent circuits are not unique. So I can not make use of the sensitivity versus a small variation of the discrete parameters and I am wondering if it is possible to apply the partial update of the LU decomposition after having replaced a subcircuit with a new one (which can also have a different number of elements). I have seen that gnucap offers some commands which allow to change the value of a discrete component but is it possible to replace an entire subcircuit ?
