Hi everyone, our team qualified for ACM ICPC world finals 2015. We qualified for WF in 2014 also but did very bad and are focusing on performing better this time. For that, many people advised us to concentrate more on geometry as they can be really tricky and can make quite a good difference in the ranklist.
Can someone post some geometry problems which involve hard concepts which can be useful for our practice? May it be previous year's icpc problems or good problems in some online judges or any good resources to learn hard geometry concepts like blogs or tutorials. Is there any place where we can find such problems?
Thanks in Advance!
Geometry problems at acm.timus are worth to have a look at them.
what about other kind of problems? do you recommend Timus for other kinds of problems as well?
You can check this collected set of problems from previous world finals contests and other resources as well:
