1) As you could see in problem "Minesweeper" some participants have got the maximum results. Now I able to use the program running time in score system. Will it be a good idea to use some time koeff in problems like Minesweeper? For example score = 200*simple_score/(200 + time), where simple_score - current score, time - program running time. On the one hand we have more fair score for the same simple_score. On the other hand some very fast solution that didn't solve some critical/hard tests can take more points than some slow, but more complicated solution. Do you have any comments on this?
2) The current contest scoring system for sure can be improved in some ways. It's more concerned to "classic" problems. I'm out of ideas right now, if you have any, feel free to post them here.
