Location of stable and unstable equilibrium configurations using a model trust region quasi-Newton method and tunnelling
… and a homotopy method for locating multiple equilibrium configurations has been proposed recently. The hybrid method combined the efficiency of a quasi-Newton method capable of locating stable and unstable equilibrium solutions with a robust homotopy method capable of tracking equilibrium …
