• Which linear programming package should I use for high numbers of constraints and "warm starts"

  - by davidsd

  I'm trying to construct a regexp that will evaluate to true for User-Agent:s of "browsers navigated by humans", but false for bots. Needless to say the matching will not be exact, but if it gets things right in say 90 % of cases that is more than good enough. My approach so far…
