Lectures on Numerical Methods, Mathematical Finance and Computational Finance

Some of my lectures are available as videos. Addition material (code) is available via Git repositories. The lecture were recorded live with a minimal post processing (removing questions from the audience, long pauses or obvious mistakes). There are still some obvious mistakes (and maybe some not so obvious ones) in there, but I tried my best. For some sessions there are multiple versions. Ofter the later version contains updates or corrections, but sometimes the previous version has additional parts that were left out in the later version. And sometime the old session was a bit better than the newer one - depending on my fitness on the day of the recording.

Coding Exercises / Assignments

An important part of the lecture are coding assignments. These assignments feature autograding using automated unit tests

Related to Computer Arithmetics

Coding Assignment: Robust solution of Quadratic Equation

This is just a warm up to make you familiar with the assignments.

Coding Assignment: Summation

This is just a warm up to make you familiar with the assignments.

Related to Monte-Carlo Method

Coding Assignment: Monte-Carlo Integration

In this assignment you should implement a multi-dimensional integration rule using a) the Monte-Carlo method and b) the Simpson's rule.

github.com/qntlb/numerical-methods-montecarlointegration-exercise

Coding Assignment: Control Variate

In this assignment you should implement a Monte-Carlo valuation of an Asian option, using variance reduction via a Control Variate, assuming a Black-Scholes models.

A control variate is model-dependent, so this Monte-Carlo valuation will lose its genericallity. This is a big disadvantage.
