Query: General cut method for computing Szeged-like topological indices with
  applications to molecular graphs   Szeged, PI and Mostar indices are some of the most investigated
distance-based molecular descriptors. Recently, many different variations of
these topological indices appeared in the literature and sometimes they are all
together called Szeged-like topological indices. In this paper, we formally
introduce the concept of a general Szeged-like topological index, which
includes all mentioned indices and also infinitely many other topological
indices that can be defined in a similar way. As the main result of the paper,
we provide a cut method for computing a general Szeged-like topological index
for any strength-weighted graph. This greatly generalizes various methods known
for some of the mentioned indices and therefore rounds off such investigations.
Moreover, we provide applications of our main result to benzenoid systems,
phenylenes, and coronoid systems, which are well-known families of molecular
graphs. In particular, closed-form formulas for some subfamilies of these
graphs are deduced.
