Well, this is where we really get to the "low effort/high impact" philosophy: The bots don't look for circles. That's too hard/I'm too lazy. So they do something much easier, and generally better: They look for a net change in heading equal to 4*360 degrees. (defn curviness "Computes the total curvature of a sequence of headings." ^double [headings] (Math/abs ^double (reduce (fn [^double sum [^double a ^double b]] (let [d (heading-diff a b)] (if (spurious-heading-diff d) sum (+ sum d)))) 0.0 (partition 2 1 headings)))) This is what allows the bots to find interesting activities I didn't think of ahead of time.
