Last December John Koza published on Youtube the four companion videos to his Genetic Programming books. These are around 1h videos that came originally as a DVD with the books. These are good videos, even though the field has progressed a lot since then, but they are very interesting to learn the essential ideas and watch the amazing set of applications Koza did. There is still much to be learned and inspired from these videos, so it’s very nice that they were made available.
