Moreover, determining the VC-dimension for set systems induced by neighborhoods of single vertices is complete for the class LogNP. In contrast to these intractability results, we show that the VC-dimension for set systems induced by stars is computable in polynomial time. For set systems induced by paths or cycles, we determine the extremal graphs G with the minimum number of edges such that VCP(G) \u0015 k. Finally, we show a close relation between the VC dimension of set systems induced by connected sets of vertices and the VC dimension of set systems induced by connected sets of edges; the argument is done via the line graph of the corresponding graph.<\/p>\n\n\n\n<p><a href=\"https:\/\/carleton.ca\/scs\/wp-content\/uploads\/sites\/260\/TR255.pdf\">TR-255.pdf<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Carleton University Technical Report TR-255 November 1994 VC-Dimensions for Graphs Evangelos Kranakis, Danny Krizanc, Berthold Ruf, Jorge Urrutia, Gerhard J.
