Description:: The goal of this thesis is to develop practical algorithms with sound theoretical properties for three different subfields of nonlinear optimization: (i) Optimization Algorithms for Supervised Machine Learning; (ii) Derivative-Free Optimization; and (iii) Distributed Optimization. As such, the thesis is divided into three main chapters. The focus of Chapter 2...

Description:: This dissertation investigates a single-column model for Arctic energy balance in the limit as a smoothing parameter associated with ice-albedo feedback tends to zero. This limit is a common modeling approximation used in conceptual climate models, and we explore the implications of taking this limit on bifurcations associated with the...
