The general formalism of the RS imaging problem presented in this paper is a structural extension of the problem considered in [4, 7, 8], hence some crucial model elements are repeated for convenience to the reader.
The problem is treated as an extension of the problem of an incompressible rubber block bonded to two rigid plates with one of the plates having a frictional interaction with the rubber block.
Particularly, it is an extension of the problem ({mathcal F}{mathcal S}_{C_{10} subseteq C_{11}} ({s_0,s_1})) [17] of which the result has been published in a good international journal by further considering a significant constraint, (C_{21}) or (C^{prime }_{21}).
In addition, we propose (3) a systematic solution to an important extension to the problem of buffer sizing combined with the ADB allocation to further reduce the ADBs to be used.
It's a symptom and also an extension of the problem.
A simple extension of the problem could be finding the optimal labeling of the vertices of the tree with nonnegative integers.
An extension of the problem at hand with heterogeneous passengers, a heterogeneous vehicle fleet, and/or multiple depots could be of interest as well.
We also discuss some extensions to the problem as directions for future research.
(Circumscription does not involve multiple extensions, so the problem emerges as the nonderivability of the conclusion that Fred is alive after the occurrence of the shooting).
Extensions of the problem can be developed that simulate realistic situations by designing complex tasks with stricter requirements.
