In numerical analysis one explores how mathematical problems can be analyzed and solved with a computer. As such, numerical analysis has very broad applications in mathematics, physics, engineering, finance, and the life sciences. This course gives an introduction to this subject for mathematics majors. Theory and practical examples using Matlab will be combined to study a range of topics ranging from simple root-finding procedures to differential equations and the finite element method.

**Linear and Nonlinear Optimization**

**(4 Credits)**

Optimization is a major part of the toolbox of the applied mathematician,
and more broadly of researchers in quantitative sciences including
economics, data science, machine learning, and quantitative social
sciences. This course provides an application-oriented introduction to
linear programming and convex optimization, with a balanced combination of
theory, algorithms, and numerical implementation. While no prior experience
in programming is expected, the required coursework will include numerical
implementations, including some programming; students will be introduced to
appropriate computational tools, with which they will gain experience as
they do the numerical assignments. Theoretical topics will include linear
programming, convexity, duality, minimax theorems, and dynamic
programming. Algorithmic topics will include the simplex method for linear
programming, selected techniques for smooth multidimensional optimization
(eg Newton's method and the conjugate gradient method), techniques for
solving for L1-type optimizations, and stochastic gradient descent.
Applications will be drawn from many areas, but will emphasize economics
(eg two-person zero-sum games, matching and assignment problems, optimal
resource allocation), data science (eg regression, convex-relaxation-based
approaches to sparse inverse problems, tuning of neural networks,
prediction with expert advice) and operations research (eg shortest paths
in networks and optimization of network flows).
