English statistician is positive to a degree (5)

leave a comment »

The occasion of this cryptic crossword was the workshop Satisfiability Lower Bounds and Tight Results for Parameterized and Exponential-Time Algorithms (Nov. 2 – Nov. 6, 2015, Simons Institute for the Theory of Computing, Berkeley, California, United States) that I had the pleasure of co-organising.

The grid is a bit more difficult than usual, with several entries less than 50% checked, and two 15-letter words. Some of the clues (and jokes) make little sense if you’re not the in target group of theoretical computer scientists.
