示例1: _spring_layout
# 需要导入模块: from sage.graphs.graph import Graph [as 别名]
# 或者: from sage.graphs.graph.Graph import get_pos [as 别名]
def _spring_layout(self):
r"""
Return a spring layout for the vertices.
The layout is computed by creating a graph `G` on the vertices *and*
sets of the hypergraph. Each set is then made adjacent in `G` with all
vertices it contains before a spring layout is computed for this
graph. The position of the vertices in the hypergraph is the position of
the same vertices in the graph's layout.
.. NOTE::
This method also returns the position of the "fake" vertices,
i.e. those representing the sets.
EXAMPLES::
sage: H = Hypergraph([{1,2,3},{2,3,4},{3,4,5},{4,5,6}]); H
Hypergraph on 6 vertices containing 4 sets
sage: L = H._spring_layout()
sage: L # random
