Before revision:  In our article, we derive a novel , fast algebraic delay analysis that nevertheless retains a high degree of accuracy . We show in extensive numerical experiments that our solution enables the analysis of large-scale networks by reducing the computation time by several orders of magnitude in contrast to the optimization analysis.
After revision:  In our article, we derive a novel , fast algebraic delay analysis that nevertheless retains a high degree of accuracy and our novel efficiency improvements reduce the cost of the analysis dramatically. In extensive numerical experiments that our solution enables the analysis of large-scale networks by reducing the computation time by several orders of magnitude in contrast to the optimization analysis.
