Hello,
Where I can find Hard DP problems using different ideas in codeforces ? Sorting the problems tagged by dp in order of submission doesn't helps, as most of them recycle a few small set of ideas again and again. Some contains some new and novel ideas (http://codeforces.com/contest/626/problem/F) and are also hard, I'm looking for such problems.
Thanks !
I am suggesting you other sources even though you need CF problems.
You can get standard DP problems in LightOj
You need to create account first
See Dynamic Programming section
Solve only those problem which are solved < 100
Hello, where I can find the editorial to the problems ? Thanks.
I think some of problem have editorial. You can search on google. Most of problem don't have. You can visit forum for some help. Thanks.
I guess you can find really awesome DP hard problems here
problems have a tag of difficulty
maybe, try those with fewer submissions instead?
