Trust region constrained algorithm
WebFirst, a common feature shared by Taylor expansions and trust-region policy search is the inherent notion of a trust region constraint. Indeed, in order for convergence to take place, a trust-region constraint is required $ x − x\_{0} < R\left(f, x\_{0}\right)^{1}$. WebMatlab Trust-region-reflective algorithm warning.
