Need some help on hard problems

I am new to programming and i could solve max 5 questions in long contest so I want to move further.
I saw on problem setting information that you may need to look into research papers to be able to solve hard problems. So what are the resources to be in touch with such papers??? Can anyone focus on this. And also if somebody can explain how challenge problems are solved too.
