Description
Event generator programs are a ubiquitous feature of modern particle physics, since the ability to produce exclusive, unweighted simulations of high-energy events is necessary for design of detectors, analysis methods and understanding of SM backgrounds. However --- particularly in the non-perturbative areas of physics simulated by shower+hadronisation event generators --- there are many parameters which must be tuned to experimental data for useful predictions to be obtained. Attempting to globally tune these parameters to a wide range of experimental results is a task much better suited to systematic, computer-based optimisation than the traditional "tweaking by eye" approach. I will present the current status of the Rivet+Professor tuning/validation system, with emphasis on recent tunes of Pythia 6 to event shape, hadron multiplicity and underlying event data from LEP to the Tevatron.
