 Jun 25 comment The expected outcome of a random game of chess? @mjqxxxx, I think it's because the chess library considers the game to be over when neither player has enough material to mate, and so breaks the loop, but doesn't consider it to be a stalemate, so it wasn't being counted correctly.

Jun 16 revised History of a combinatoric problem: exchanging numbers by throwing stones Correct spelling of username Jun 16 asked History of a combinatoric problem: exchanging numbers by throwing stones Jun 12 comment How do you create a nonlinear game that the player can always win? The way to maximise the non-linearity is to minimise the interdependence of the puzzles. The point I'm hoping that you'll take away is that you need to rethink your goal.

And as a hint: have you tried building a non-deterministic push-down automaton to recognise this language? May 21 comment What is one way to prove that there exists no ellipse that matches the exact curvature of the sin wave? That doesn't rule out the sine wave being less than half of an ellipse. May 16 comment what is the minimum value of the angles inside these triangles? I think the question is: what is the smallest angle $\alpha$ such that there exists a dissection of the square into triangles satisfying two properties: that none of the triangles has an internal angle greater than $\alpha$; and that no vertex of a triangle touches another triangle except at a vertex. If so, there's an easy lower bound of 67.5 degrees.
