Mobile phones, ATMs, modern cars, televisions, e-readers: none of them would work without software. The heart of software is formed by algorithms: step-by-step procedures to perform given tasks.
You have a job interview in 20 minutes and you are in a hurry to arrive at your application in time. To make matters even more stressful, there are many routes to your destination, but you have no idea which one to select. Luckily, you have access to a navigation system that can help you in your route selection process.
Alfred Aho and Jeffrey Ullman received the 2020 A.M Turing Award for their contributions to computer science. Let’s explore how their contributions have shaped the principles, techniques and tools for writing compilers.
In times of war, secure communication can be the difference between life and death, or even winning or losing a war. The first to patent a rotor machine in Europe was Arthur Scherbius in 1918. Scherbius’ version of the rotor machine became a commercial success, unlike the other patented machines. Scherbius named his machine Enigma.
Recently there has been a breakthrough in the field of algorithms for geometric network problems, concerning the complexity of the Euclidean Travelling Salesman Problem.
We might not be fully aware of it, but we all use wireless communication everyday in many familiar situations, such as when we connect our laptop to the local Wi-Fi network, when we use navigation apps to orientate ourselves while driving, or when we send a message to a friend using our smartphones. It has become so natural for the world we live in, that we often take it for granted and have no idea of how it works.
