| For an arbitrary invariant $\rho(G)$ of a graph $G$ the $\rho$-edge adding stability number $eas_{\rho}(G)$ is the minimum number of edges of the complement $\overline{G}$ whose addition to $G$ results in a graph $H \supseteq G$ with $\rho(H) \neq \rho(G)$. If such an edge set does not exist, then we set $eas_{\rho}(G) = \infty$. In the first part of this paper we give some general results for $eas_{\rho}(G)$. We prove among others a Gallai's theorem type result for invariants that are based on the $\rho$-edge adding stability number. | ||
