A -step generalization of the Q-order of convergence
Gabriel Jarry-Bolduc
The notion of Q-order convergence is arguably the most important tool for describing the asymptotic behavior of a convergent sequence. Loosely speaking, it captures the``speed''of…

Using generalized simplex methods to approximate derivatives
Gabriel Jarry-Bolduc, Chayne Planiden
This paper presents two methods for approximating a proper subset of the entries of a Hessian using only function evaluations. These approximations are obtained using the technique…

Using orthogonally structured positive bases for constructing positive -spanning sets with cosine measure guarantees
Warren Hare, Gabriel Jarry-Bolduc, Sébastien Kerleau +1
Positive spanning sets span a given vector space by nonnegative linear combinations of their elements. These have attracted significant attention in recent years, owing to their ex…
