A Switching Criterion in Hybrid Quasi-Newton BFGS - Steepest Descent Direction

Two modified methods for unconstrained optimization are presented. The methods employ a hybrid descent direction strategy which uses a linear convex combination of quasi-Newton BFGS and steepest descent as search direction. A switching criterion is derived based on the First and Second order Kuhn-T...
