2. A configuration of 4027 points in the plane is called Colombian if it consists of 2013 red points and 2014 blue points, and no three of the points of the configuration are collinear. By drawing some lines, the plane is divided into several regions. An arrangement of lines is good for a Colombian configuration if the following two conditions are satisfied: • no line passes through any point o...
متن کاملThe International Olympiad in Informatics Syllabus

4. Let P be a point inside triangle ABC. The lines AP, BP, and CP intersect the circumcircle of triangle ABC again at the points K , L , and M , respectively. The tangent to at C intersects the line AB at S. Suppose that SC = SP. Prove that MK = ML. 5. In each of six boxes B1, B2, B3, B4, B5, B6 there is initially one coin. There are two types of operation allowed: Type 1: Choose a nonempty box...
متن کاملBuilding the Network Infrastructure for the International Mathematics Olympiad
In this paper we describe the network infrastructure we designed, built and operated for the International Mathematics Olympiad in the Netherlands in 2011. The infrastructure was pragmatically designed around OpenVPN tunnels in a star topology between the various venues. VLANs were extensively used to separate functional groups and networks. The actual construction of the event network took abo...
