Query: Multi-UAV Routing for Persistent Intelligence Surveillance &
  Reconnaissance Missions   We consider a Persistent Intelligence, Surveillance and Reconnaissance (PISR)
routing problem, which includes collecting data from a set of specified task
locations and delivering that data to a control station. Each task is assigned
a refresh rate based on its priority, where higher priority tasks require
higher refresh rates. The UAV team's objective is to minimize the maximum of
the delivery times of all the tasks' data to the control station, while
simultaneously, satisfying each task's revisit period constraint. The
centralized path planning problem for this PISR routing problem is formulated
using mixed integer linear programming and solved using a branch-and-cut
algorithm. Heuristics are presented to find sub-optimal feasible solutions that
require much less computation time. The algorithms are tested on several
instances and their performance is compared with respect to the optimal cost
and computation time.
