William submitted a Comment to Problem 44764. Lights Out 10 - 5x5, with wrapping, 6 moves

The first test suite problem is troublesome because it requires only 3 moves, and the 3-move solution is not necessarily the first one it finds that has 6 moves or less.

William submitted a Comment to Problem 44895. Determine roll pitch yaw angles from a 3D rotation matrix

There is a flaw in the test suite. It tests the values in rpy2r rather than the results rpy from the solver's function. Also, the tolerance needs to be widened a bit.

William submitted a Comment to Problem 44893. Create a 3D rotation matrix from roll-pitch-yaw angles

The variable name rpy suggests that the order is [roll, pitch, yaw], but that's not correct, is it?
