A multi-precision quadratic regularization method for unconstrained optimization with rounding error analysis

Dominique Monnet and Dominique Orban

We propose a multi-precision extension of the Quadratic Regularization (R2) algorithm that enables it to take advantage of low-precision computations, and by...

Complexity of trust-region methods with potentially unbounded Hessian approximations for smooth and nonsmooth optimization

Geoffroy Leconte and Dominique Orban

We develop a worst-case evaluation complexity bound for trust-region methods in the presence of unbounded Hessian approximations. We use the algorithm of ...
