Messed-up late night thoughts
Feb. 9th, 2005 12:15 pmI had trouble sleeping last night, because my mind drifted off to a problem, which I record below. I make no guarantees with respect to coherence :)
Say that you have a set of tuples (p, u, v), where p is a point on the x-y plane, u and v are positive integers, and u > v. One of the tuples is the origin tuple, (p0, u0, v0), and no two tuples share the same point.
A run is a nonrepeating sequence of n such tuples (pi, ui, vi), starting with the origin tuple, where any sum u0 + v1 + v2 ... + vi is at least ui+1.
Let's say the length of the run is the sum of all the distances between adjacent pi and pi+1 points in the sequence, and the size of the run is the sum u0 + v1 + v2 ... + vn.
( the actual problem, maybe )
Then my head went "BA-NA-NA" and I decided I should forget about this and go to bed. Maybe I'm mad.
