Recently I decided to move my 24 the math game solver and solutions from ocf.berkeley.edu here. Not that there is anything wrong with The OCF, I love the ocf and the idea of independent student-run services. The only concern is that the ocf service is not always as stable as I’d like it to be.
And I will put more effort in reducing more redundancies in the solutions. Another thing to do in the future is to code up an interactive solver in HTML5.
