Please take a look at my timetable / availability
before trying to reach me in person!

Welcome to my homepage. Don't expect too much from it, since the page is the result of twenty minutes spare time. You will only find some links I like and the description of some of my work.

Short guide for pronouncing my last name: Fleegue. Fl like in flying, ee like in beer, ge like in fatigue.

Short guide for pronouncing my first name: York.  Like in Yorkshire. That will do.

Two not-so-short guides for pronouncing my first name: 
First version, York: the Y like in Yorkshire, but ork like in work. Pretty good.
Second version, Yirk: the Y like in Yorkshire, ir like in bird, k like in work. Just in case you want to impress me.  :-)


Stuff I actually deemed so important that I took some pains to bring it into a presentable form, and that was deemed so important by other people that it got published.

Awards and Invitations

Shameless self-promotion here. Moreover, been there, done that.

Talks and Attended Conferences

Again: Been there, done that. Where "that" actually means giving a talk. Among other things.

Multi-Hop Ad-Hoc Wireless Networks

I am interested in mathematical algorithms useful for the design and the optimization of multi-hop ad-hoc wireless networks, especially with respect to routing, power control, decomposition approaches, etc. Most of these algorithms have to work in a distributed fashion in a real-time environment, so their design can be considered as hard. My work is mainly done in conjunction with industrial partners like Alcatel-Lucent, Bell Labs, Qualcomm, etc.

Efficient Algorithms for Multiobjective Optimisation Problems

In multicriteria (multiobjective) optimization, several objective functions have to be minimized simultaneously. Usually, no single point will minimize all given objective functions at once, and so the concept of optimality has to be replaced by the concept of Pareto-optimality or efficiency. A point is called Pareto-optimal or efficient, if there does not exist a different point with the same or smaller objective function values, such that there is a decrease in at least one objective function value. Two different efficient points will usually be not only quite different from each other in terms of objective function values, but also incomparable with each other: it will not be the case that one point is better than the other one with respect to all objective functions involved. Instead, the quality of the points will change across different objectives. Therefore, we have to gain as much information as possible about the solution set of a given problem, preferably by constructing a well-defined approximation to it.

Modeling and Locating Air Polluting Facilities: the OLAF software

The OLAF software models the effects of a low-toxic air pollutant on inhabitants of arbitrary land-based ecosystems and optimizes the location of the polluting facility.

Integration Nodes for the Sphere

Here you can find more information about one of my current research interests. If you need to integrate functions defined on the two-dimensional sphere $S^2$, this might be what you are searching for.

A Problem Generator

I was rather angry when I wrote this little piece. Please bear with me.

On-line Bibliographies

Search some (rather old) bibliographies (in BibTeX format) online and look at some links to other projects of this kind.

Jumping-Off Points

Some of my old starting points on the Web. Outdated. They can also be used for searching specific subjects.


Some links to mathematics I am interested in. Utterly and totally outdated.

Back to top.

Back to CORMSIS.
