Well-structured problems (also called well-defined problems) have clear solution paths: the problem solver is usually able to specify, with relative ease, all the steps that must be taken to reach a solution.
That said, the major question we are facing becomes clear: Which path solves the problem the best?
In general this is an NP-hard problem, but, by setting an upper limit on path length the problem is computationally tractable.
Using the concept of paths, the GKO problem is rewritten to an equivalent nonlinear programming problem.
"It gives each side a clearer path to resolving the problem," Mr. Gitter said.
By connecting the stationary locations using the nearest neighbor strategy, we form the initial guess for the path planning problem of the mobile sensor.
In particular, the present work addresses the path following problem, applying the control paradigm of prioritized tasks, usually exploited for robotic manipulators.
By using these planned tool paths, the overcut problem is eliminated and the machining errors of contact area are reduced.
Motivated by these studies, we use relay networks to solve the path loss problem in the long distance transmission.
When a delay constraint is imposed on each path, the maximum flow problem is NP-hard.
