VertexConnectivity returns the vertex connectivity of a graph, that is the minimum number of vertices whose removal disconnects the graph. When I was filtering some graphs with a certain vertex connectivity, maple was much slower than mathematica. I'm going to store all graphs in file named op21new.g6. When mathematica selects all graphs with a connectivity of 6, it only takes 15 seconds to complete.
mma codes are the following
L = Import[
"C:/Users/asus/Desktop/op21new.g6"]; # Change this line
t = AbsoluteTiming[L1 = Select[L, VertexConnectivity[#] == 6 &];]
But my maple has been running for half an hour and it is not over yet.
L:=ImportGraph("C:/Users/asus/Desktop/op21new.g6", graph6, output=list): # Change this line
Because Mapleprimes does not support graph6 format file uploading, I changed it to TXT format. If you want to use it, you only need to change the suffix name.
