Regarding this week's lectures
A recording for thursday's exercise session can now be found in the "timeplan". Regarding tomorrow's lecture, don't be scared about the proof that Bland's rule does not cycle: This is very technical, and not suitable as an exam question.
Note also that I have put out a file where you can run several of the exercises for this week using the simplex1-implementation of the simplex method (exercises_week3). I have also improved and documented simplex1. I will wait translating this to Python to when we come to the point where we make the simplex method more robust (chapter 6).
