Has anybody competed in this earlier? Is it a good contest?
From my experience — sometimes problems are more or less standard ACM tasks focused on math (like last task from Ad Infinitum 9, which I solved with pretty standard ACM technique), in other cases you'll face completely different tasks — where OEIS and long staring at results of brute-force solution is only way for me to find a solution, and even after reading an editorial it still looks like some math magic :) And for both types — there are lot of contestants who like them.
So I would say — yes, I competed in it few times before, and it is a good contest, try it :)
Is there some system of reminders about Ad Infinitums? I participated 5 times in a row, but I think that I didn't miss any of them because of your blogs on CF and it can be the case that someday I will just miss them.
