Stochastic Differential Equations —The Ornstein-Uhlenbeck Process

I haven’t written for a few months and while I was previously writing about optimization and linear programming, this article will not be about that. This article is about the basics of stochastic differential equations and something called the Ornstein-Uhlenbeck process. …

Linear Programming — The Corner Point Method

I haven’t written anything on here since June 2020. I had originally planned to write some more about linear algebra and I’m not sure what happened. In college I briefly did some research on using linear programming to help reduce noise in signals. At that point I don’t think I…

Linear Programming — Multiperiod Inventory Problem

The following is meant to continue some of the work I had been doing in these two articles I wrote (https://medium.com/star-gazers/linear-programming-multiple-plant-models-360885518829 and https://medium.com/star-gazers/linear-programming-the-corner-point-method-3af2a96b6a62). Background In these articles I introduced some basic ideas about linear programming models using some fictional water plant. The original problems are in block quotes below.
