Ideal order of solving in contests with scores.

Автор donpaul2718, история, 4 часа назад, По-английски

Is there any advantage in solving questions in a non-standard order in normal div2? In div4, div3 and div2 edu it's obvious that we gotta go from easy to hard as it reduces time penalty. But in normal div2 it's hard to tell. For example score for a 1500 question decays way faster than that of 1000 or 500 rated ones. So I am assuming there is some benefit in attempting those first?

I think generally going from the easiest to the hardest is the most optimal.

I know 2 strats with weird solve orders:

1) Skip the problems you are stuck at and return to them later. Sometimes I was solving in order BDAC. In my experience it is extremely effective.

2) Solving contest starting from E, and skipping the contest if you dislike the problem, if you have not sent anything you rating wont be affected. It is probably effective, but kinda unethical and very stressful imo

    What's so unethical about the second option?

Well, you can calculate it yourself, taking your average solving time per problem, and using a little bit of math. The loss for A per minute is 2, for B is 4, for C is 6 and so on. As a basic example, if you are able to solve all problems in slightly same time, like 2-3 mins for a problem, then It's beneficial to start from the hardest(hardest you can solve).

Or don't waste your time on these shenanigans and practice instead, going greedily A -> B -> C -> ...
