In this section we describe the results obtained after applying the competition approach that has been described in previous section. This approach has been performed along five courses in the last ten years (2000e2009) and here we can see the feedback, the data and the statistical graphics for those years, together with some opinions from the surveys fulfilled by the students in the last three courses where the competition approach has been performed. Next, every one of those three courses is described including: an introduction to the lab work proposed, the algorithms provided by the groups that won the tournament, and the results of the survey answered by the students.
