As a software developer, there isn't a single programming concept / architecture / algorithm / etc that I can't learn in less than a day. The following algorithms have beaten me totally and I wasn't able to implement them: Bochs multiple shooting (the modern versions are even more complex): http://www.iwr.uni-heidelberg.de/groups/agbock/FILES/Bock1984.pdf http://www.iwr.uni-heidelberg.de/groups/agbock/FILES/Bock198...
