Deterministic optimum designs that are obtained without consideration of uncertainties could lead to unreliable designs, therefore calling for reliability-based design optimization (RBDO). However, it has been reported in literatures that when RBDO involves evaluation of probabilistic constraints it is prohibitively expensive or even diverges for many large-scale applications. Therefore, the hybrid...
A comparison is undertaken of a number of algorithms for profile reduction of sparse symmetric banded positive definite matrices based on results reported in the literature, with regard to the profile reduction and the execution time. A simple methodology is also proposed to facilitate the selection of appropriate profile reduction algorithms for a given application. This methodology takes into...
