Graph theoretical results obtained by the support of the expert system “Graph” -- an extended survey. GRAPH is an interactive package, developed as an expert system in the 80s at the University of Belgrade, aimed to support research in graph theory by helping to pose, verify or disprove conjectures. The present article surveys 92 papers, mostly in spectral graph theory, which results were obtained with the support of GRAPH. The results presented are divided into the following sections: Tables of graphs. The largest eigenvalue of a graph. The second largest eigenvalue of a graph. Graphs with least eigenvalue bounded by $-2$. Integral graphs. Graph angles. Star complements. Graphs sharing specified properties with their complements. Miscellaneous results. Combinatorial optimization.
