We investigate the performance of a combination of sophisticated local symmetric ordering methods with a simple symmetrization step on a test set of Jacobians obtained from modified nodal equations. It is demonstrated that using such ordering heuristics as a replacement for Markowitz’ algorithm may accelerate circuit simulation significantly.

Classical mean variance utility of Markowitz [1952] and Tobin [1958] have relied on objective expected utility hypothesis. This paper presents a choice-based axiomatization of mean variance utility, in a Savage-type setting of ambiguity, which neither assumes nor implies that individual’s preferences over portfolios conform to the expected utility hypothesis.
Departure from normality poses implementation barriers to the Markowitz mean-variance portfolio selection. When assets are affected by common and idiosyncratic shocks, the distribution of asset returns may exhibit Markov switching regimes and have a Gaussian mixture distribution conditional on each regime. The model is estimated in a Bayesian framework using the Gibbs sampler. An application to...
