Comment (by pramsey):
OK, two cases here: the tolerance value is smaller than the size of most
arcs, in which case just simplifying the linear bits might make sense, and
linearizing the arcs first would be a Bad Idea. Second case, the tolerance
value is much bigger than the arcs, so they should get wiped away and
replaced... by what? Here linearizing at least forces a common logic onto
the whole problem. Trying to reason about DP and arcs doesn't work so
good, since DP assumes you can fit the inputs into a linear sleeve.
