Optimization through first-order derivatives

WebThe second-derivative methods TRUREG, NEWRAP, and NRRIDG are best for small problems where the Hessian matrix is not expensive to compute. Sometimes the NRRIDG algorithm can be faster than the TRUREG algorithm, but TRUREG can be more stable. The NRRIDG algorithm requires only one matrix with double words; TRUREG and NEWRAP require two … WebOct 6, 2024 · Optimization completed because the objective function is non-decreasing in feasible directions, to within the value of the optimality tolerance, and constraints are …
