  The concept of generalized path algebras was introduced in (Coelho and Liu,
2000). It was shown in (Ib\'a\~nez Cobos et al., 2008) how to obtain the
Gabriel quiver of a given generalized path algebra. In this article, we
generalize the concept of generalized path algebra to allow them to have
relations, and we extend the result in (Ib\'a\~nez Cobos et al., 2008) to this
new setting. Moreover, we use the extended result mentioned above to address
the inverse problem: that is, the problem of determining when a given algebra
is isomorphic to a generalized path algebra in a non-trivial way.
