What was your favourite problem in 2017?

Revision en1, by Morphy, 2017-12-31 15:58:13

2017 was a prime year with great contests and some notorious coincidences.

From the problems that I proposed, my favourite was BCYCLES, it is about covering twice every edge of a bicubic graph using cycles. The idea was colouring the edges with 3 colours and then make the cycles using alternating colours.

From problems that I saw in CodeForces my favourite was Symmetric Projections, IMHO it is not a hard problem, but I liked the property that every axis with momentum 0 passes through the center of mass.
