Robert Luce (Gurobi) experiments with and sees some potential in using GPUs for LP solving, but it does not seem to be overwhelming (currently the potential for MIP solving is unclear)

I remember when I presented GCG 3.0 at the MIP conference in 2018, today Erik Mühmer introduces the new features of the next version

wenn die "Nachleerung" der ein- bzw. zwei- oder vierwöchigen Tonnen eine bzw. zwei oder vier Wochen später stattfindet, dann ist das keine "Nachleerung", sondern die reguläre; die Leerung am Streiktag ist damit ersatzlos ausgefallen

one of my master's students displayed (wide and very long) heat maps in his thesis that always looked like knitting patterns to me; I suggested to him to make a scarf out of this.

well he did. thank you, Alex, for a very very nice gift! #orms
