After going to the problemset just click on the tag you want (in the same line of the problem name in gray) then a list of all problems which has the same tag will appear. Or if you know the tag you can put it in the link, for example : for greedy problems write the link : http://codeforces.net/problemset/tags/greedy And for data structure problems write the link: http://codeforces.net/problemset/tags/data%20structures and so on
