Peng Liu submitted a Comment to Solution 1316777

Thanks for your comment. I was confused by the original problem description such as "state 0: legal 1: this state", where the extra colons seem to be misleading. After some digging, I have figured out the rationale of Tic-Tac-Toe, and thus, updated my solutions.

Peng Liu submitted a Comment to Problem 44353. Group-wise Euclidean distance

Thanks for your feedback. That stray answer tried to hack the scoring in the test suite, and is now removed. Unfortunately, the current scale of the score map is still not good (hard to distinguish good solutions with score < 50). A possible workaround (from a user side) is to modify the scoring in the test suite to truncate the high scores (>=100) to 100, and the resulting y-axis scale would be [0,100] (which makes all solutions distinguishable). But this also results in a re-scoring of all solutions, which might change the current ranking of those similarly fast solutions (e.g., the current best two solutions have an equal score of 2)... I would appreciate any further suggestions (or comments from the Cody admin side) on this.
