Question
(Dynamic Programming.) A group of friends is visiting a number
of attractions located along a highway, starting at kilometre 0, placed at distances
ɑ1 < A2 < ··· <an. They may chose which attractions to visit, and they must
finish by visiting an, which is their destination. They must visit one attraction a
day. The distance of the attraction i from the starting point is a₂. They want to
cover 200 kilometres a day, however this may not be possible, depending how far are
the attractions from one another. If they drive a distance d during any day, they
receive a penalty of (200 - d)². Their goal is to plan the drive by minimizing the
total penalty, that is the sum over all travel days, of the daily penalties. Give an
efficient algorithm that determines the optimal sequence of attractions to visit.
