To become a German citizen with the accelerated three-year application process, I had to take the German C1 exam (language proficiency) and the Einbürgerungstest, a kind of…

Multi-fidelity Optimisation: The art of skimming

Algorithms

If you had 3 days to find the best book in a pile of 100 books with unknown authors and titles, how would you do it? You would not have the time to read all of them from…

Black-box Optimisation: Searching in the Dark

Algorithms

The previous articles on optimisation showed that we could leverage information about optimisation problems to solve them quicker. But what if we have no or very little…

Linear Programming: Optimisation at the Edges

Algorithms

In continuous optimisation problems, it is impossible to try all combinations. But what if a problem could be solved simply by evaluating the corners of the feasible region?…

Little by Little: Optimisation with analysis and gradients

Algorithms

Problems for with a known objective function or observable gradient is known can be solved efficiently through analysis or gradient descent/ascent.

The Intuition Behind Optimisation

Algorithms

What should I do with my life? What broadband internet subscription should I choose? Most of our daily problems can be framed as optimisation problems.

What is Algorithm Complexity?

Algorithms

The third lecture of the semester had just started. I was still a young lecturer full of hope and naive optimism. After 10 minutes of going through the maths of asymptotic…

Big Oh, Big Omega, Big Theta: What is asymptotic notation?

Algorithms

Computer Scientists use asymptotic notation is to bind algorithmic complexity expressed as a function of its input size. Instead of focussing on a function’s exact…

What is the Complexity of Euclid’s Algorithm?

Algorithms

Euclid’s algorithm is one of the earliest algorithms ever recorded. It finds the Greatest Common Divisor or “GCD” between two integers \(a\) and \(b\) with \(a > b\). As an…

How to analyse the complexity of a Python code snippet?

Algorithms

There is a lot of theory behind algorithm analysis and complexity. But how do these concepts relate to the code you are writing every day?

Smart Algorithms Use Meta-Information to Solve a Problem

Algorithms

While preparing for the introductory lecture of Algorithms and Programming, a course I was about to teach, I was struggling to find the core idea that would bind the…
