I've been trying to solve this problem from the South America ICPC 2009: https://www.urionlinejudge.com.br/judge/es/problems/view/1412
I am completely stuck and I can't seem to find the solution. It kinda feels like it's some form of DP but I can't seem to find a recurrence that works. Do you have any ideas or hints?
Thank you so much!
Hi,
I'm trying to solve Antenna in the Cinoc Mountains from UVa.
I don't know how to find the intersection between a segment and a cone. Can anyone point me in the right direction?
Thanks.
