Dr. Wolfgang Fink is the WINNER of the Congress on Evolutionary Computation (CEC) 2006 Huygens Probe Competition, which was held at the World Congress on Computational Intelligence (WCCI) 2006 in Vancouver, BC, Canada from July 16-21, 2006

"In this competition you will be given access to a series of 20 "moons"- fractal landscapes (generated by sequences of meteor impacts) that are wrapped in both x and y dimensions. [...] For each moon you will be allowed 1000 probes (evalutations) to find the lowest point on the surface that you can. You may use any technique at your disposal.

The scientific aim is to allow comparison of the many evolutionary (and other more traditional) approaches to real-valued (non-differentiable) optimisation, given a fixed resource in the number of evaluations, and to better understand the cost/benefit trade-offs of population based methods.

For the competition, access will be given to a new set of 20 unseen moons from the same sequence used for benchmarking. Each individual or group will be allowed to enter up to three algorithms.

Unlike the benchmarking where an absolute score is generated, the competition will use a ranking system where the entries are compared directly against each other for performance on each moon. All entries will be ranked for their performance on each of the 20 moons, and the algorithm with the highest overall average ranking will be the winner".
