Question

我必须在网络增长的某些步骤（即N = 100，N = 1000，N = 10000等）测量Barabasi Albert图的某些性质，如度分布。我知道如何使用networkx生成这样的图表，但我真的不清楚如何在增长过程中访问这些属性。

没有代码可以显示给你，我需要提示算法本身，一些例子将非常感激。我使用的是Python 2.7，但如果有必要，我也很满意R.

Answer 1

我认为您正在寻找的功能是Barbabasi Albert Graph function netwrokx。在查看上述函数on this link的源代码（基于networkx文档）时，注释中给出了步骤。您可以在while source<n:循环的每次迭代中打印图表的属性，以获得所需的属性。

Answer 2

根据@Mohammed Kashif的回答，这里是Barabasi Albert图的修改后的源代码，它返回一个字典数量的字典，其值为数组：

g,d = barabasi_albert_graph_modified(10,2)
#out:
#{3: array([1, 1, 2]),
# 4: array([1, 2, 2, 3]),
# 5: array([1, 2, 2, 3, 4]),
# 6: array([1, 2, 2, 2, 4, 5]),
# 7: array([1, 2, 2, 2, 3, 4, 6]),
# 8: array([2, 2, 2, 2, 2, 3, 4, 7]),
# 9: array([2, 2, 2, 2, 2, 2, 4, 5, 7]),
# 10: array([2, 2, 2, 2, 2, 2, 3, 4, 5, 8])}

让我们试一试：
