Just some stuff I find interesting/useful/can't remember. Permanently WIP
Nonlinear Optimization
Convexity theory, extensions, applications. Descent,
trust region, interior point, and ellipsoid methods. Non-convex continuous optimization. Combines CO 463/466/471 (+ my own commentary).
Linear Algebra
Anthology of various linear algebra theorems I can't remember. Focuses on stuff useful for
optimization/machine learning. To be uploaded.
Other cool stuff I want to get better at: Pólya enumeration (and other counting stuff). Differential Geometry. Spectral graph theory.
