Predicting outcomes of tennis matches

In the article posted 4 weeks ago about the dark side of the tennis world I talked about how vulnerable the tennis sport is to match fixing. Bets can even be placed on every single point. However, is there a way to predict the outcome of matches and maybe even points? There are multiple articles that have tried to solve this problem. Many of these articles mention Markov models as I explained earlier. Now I will be digging deeper into this subject and try to predict a match between Rafael Nadal and Roger Federer. Markov […]

AlphaZero: the new king of chess

It may seem like a guy with a really curious last name gave his child an even weirder first name, but AlphaZero is actually the name of the computer program developed by DeepMind (owned by Google). This year, this program managed to shock the chess world by beating Stockfish 10, which used to be the strongest chess engine in the world. To make this performance even more impressive, it took AlphaZero only four hours to become this good at chess. Checkmate humans, your time is over. AlphaZero vs. Stockfish This is not the first impressive […]

Introduction to Mathematical Cycling

It is a remarkable sport, time trial cycling. It seems comparable to road racing and at the same time it has nothing to do with it. In a road race one tries to conserve energy as long as possible, while during a time trial you want to use all the power you have got during the whole event. Spending 200 hours in a wind tunnel during the winter months to find out that you have to adjust your shorts length with four millimetres. Crazy things like switching your socks five minutes before the start of […]

Citius, Altius, Fortius – Blijven we records breken?

“Citius, Altius, Fortius” is het motto van de Olympische Spelen. Het betekent “Sneller, Hoger, Sterker” en het lijkt of atleten elke Spelen prestaties neerzetten die aan dit motto voldoen. De eerste “moderne” Olympische Spelen vonden al plaats in 1896, maar tegenwoordig worden elk jaar nog steeds veel wereldrecords verbroken. Is het toeval dat bijna alle staande wereldrecords zo recentelijk behaald zijn, of zijn hier oorzaken voor? Dat bij sommige sporten prestaties telkens beter worden is klaarduidelijk; de uitrusting van sporters wordt steeds beter. Skiërs konden vijftig jaar geleden simpelweg niet zo snel de berg af komen […]
