一个数学题貌似EP-3比EP-2没啥实质进步啊

Is this a NP-complete problem?今天ebay的epl1算deal吗?

这个该死敌教授上课从来不将这些,可作业全是这些题,拜托了:
Consider a network where the weight on the link represents the delay
on that link and it varies with time. Suppose that between a specified
source-destination pair (s,d) there are r different paths, P1,
P2,...Pr.
The path lengths are denoted PL1, PL2, ... PLr. Time is measured in
discrete slots from 1 to T. Since the link weights change with time,
the
length of the paths also change with time. The shortest path length
from
s to d at any time t is denoted by Popt(t

you can check with books on approximation algorithms
for NP hard problems.
