Convergence Properties of the Nelder--Mead Simplex Method in Low Dimensions
TL;DR: This paper presents convergence properties of the Nelder--Mead algorithm applied to strictly convex functions in dimensions 1 and 2, and proves convergence to a minimizer for dimension 1, and various limited convergence results for dimension 2.

Estimating Solutions of First Kind Integral Equations with Nonnegative Constraints and Optimal Smoothing
TL;DR: In this article, a method for estimating solutions of Fredholm integral equations of the first kind, given noisy data, is presented, where regularization is effected by a smoothing term which is the $L^2 $-norm of the estimate.
