  2. Nikolaj Van Omme

    Nikolaj Van Omme

    Expert Mathematical Modeller and Optimization Specialist

    Canada

    Hi there, My name is Nikolaj and I'm a passionate problem solver. My background is both in mathematics (MD in pure maths, PhD in applied maths) and computer science (MD in computer science) and I have over 15 years of programming experience. My speciality in optimization is Arc Routing. I love to create complex algorithm and solve "impossible" problems. My computer science skills are not only theoretical (algorithm analysis, algorithm creation, heuristics tuning) but also practical. I have worked on several (big) industrial projects. Let me shortly present one success story. Challenge: Optimize the traffic lights for a city of the size of Brussels. The idea was to coordinate intelligent traffic lights to minimize the total travel time of the users. I had the pleasure to supervize a team of two and we managed to reduce the total waiting time by 30%. In my PhD thesis, I defined a new optimization problem (The Cumulative Chinese Postman Problem), studied its complexity, proposed 8 different models (out of 20!) and studied their relative strengths both theoretically and experimentally. The algorithms that I have developed were 2 to 133 faster than the state of the art solver at the time (2011). In short, I'm a perfectionist that enjoys solving complex problems.
