    A separated graph is a pair \((E, C)\) consisting of a directed graph \(E\) with the set of vertices \(E^0\), and a set \(C=\bigsqcup_{v\in E^0}C_v\), where each \(C_v\) is a partition of the set of edges whose terminal vertex is \(v\). In [Adv. Math. 252, 748--804 (2014; Zbl 1319.46046)], the authors have introduced a modification \(O(E,C)\) of the graph \(C^*\)-algebra (the quotient of the latter under certain relations) called a tame graph \(C^*\)-algebra. The paper under review is devoted to evaluation of the \(K\)-theory groups of tame graph \(C^*\)-algebras in the case when all sets in \(C\) are finite.
