A real world competition isn’t a random sample of anything. It’s a selection of some problems, with some data. The performance of any algorithm will depend on fit to those problems, with those data.
My takeaways from the NFL theorems—the problems in the real world are some structured subset of all possible problems, and the performance of any generalizer for a problem will depend on fit to that problem.
