如何在python-igraph中播种图生成器? [英] How to seed graph generator in python-igraph?

问题描述

是否有任何方法可以播种以下使用python-igraph生成的Watts-Strogatz图，以便每次运行脚本时都获得相同的SW图实现?

Is there any way to seed the following Watts-Strogatz graph generated using python-igraph, so that each time I run the script I get the same realization of SW graph ?

import igraph
graph = igraph.Graph.Watts_Strogatz(1, N, nei, p)

其中N是节点数，nei所连接的邻居数，以及p的重新布线概率.

where N is the number of nodes, nei the number of connected neighbors, and p the rewiring probability.

推荐答案

igraph使用Python的内置RNG，因此您可以播种该种子:

igraph uses the built-in RNG of Python so you can seed that:

In [1]: import random
In [2]: random.seed(1234)
In [3]: g=Graph.Watts_Strogatz(1, 100, 2, 0.25)
In [4]: random.seed(1234)
In [5]: g2=Graph.Watts_Strogatz(1, 100, 2, 0.25)
In [6]: g.get_edgelist() == g2.get_edgelist()
Out[6]:  True
