randomEdgeIdeal -- Creates an edge ideal from a random graph with n vertices and t edges.

Synopsis

• Usage:

  (I,G) = randomEdgeIdeal(n,t)

• Inputs:
  • n, an integer, number of vertices
  • t, an integer, number of edges
• Outputs:
  • I, an ideal, a random edge ideal
  • G, a graph, the graph underlying I
