I've recently started solving problems on AtCoder and noticed that the quality of problems is exceptional. Obviously Codeforces also offers great problems, AtCoder's seem to be on another level. Does anyone know why this might be? One possible reason could be that AtCoder hosts contests less frequently than Codeforces, allowing them to maintain a higher standard for problem quality .

Does anyone know why there has been a (relative) decrease in frequency of contests recently :(

Does anyone know if there would be regular contests during the Huwei ICPC challenge(which will run for 2 weeks) or not??
