GenGrid¶
- GenGrid(GraphType, Rows, Cols, IsDir=True)¶
Generates a two-dimensional graph of rows and columns specified by Rows and Cols parameters.
Parameters:
- GraphType: graph class (input)
Class of output graph – one of PNGraph, PNEANet, or PUNGraph.
- Rows: int (input)
Specifies number of rows for graph.
- Cols: int (input)
Specifies number of columns for graph.
- IsDir: bool (input)
Indicates whether the edges should be directed or undirected. Defaults to directed.
Return value:
- graph
A Snap.py graph of the specified type.
The following example shows how to generate grid graphs for classes TNGraph, TUNGraph, and TNEANet:
import snap
Graph = snap.GenGrid(snap.PNGraph, 10, 12, False)
for EI in Graph.Edges():
print "edge: (%d, %d)" % (EI.GetSrcNId(), EI.GetDstNId())
UGraph = snap.GenGrid(snap.PUNGraph, 10, 12, False)
for EI in UGraph.Edges():
print "edge: (%d, %d)" % (EI.GetSrcNId(), EI.GetDstNId())
Network = snap.GenGrid(snap.PNEANet, 10, 12, False)
for EI in Network.Edges():
print "edge: (%d, %d)" % (EI.GetSrcNId(), EI.GetDstNId())
