示例1: testDensity
# 需要导入模块: from apgl.graph.DictGraph import DictGraph [as 别名]
# 或者: from apgl.graph.DictGraph.DictGraph import density [as 别名]
def testDensity(self):
numVertices = 10
graph = DictGraph(True)
for i in range(numVertices):
graph.setVertex(i, 0)
graph.addEdge(0, 1)
self.assertEquals(graph.density(), float(1)/45)
graph.addEdge(0, 2)
self.assertEquals(graph.density(), float(2)/45)
graph = DictGraph(False)
for i in range(numVertices):
graph.setVertex(i, 0)
graph.addEdge(0, 1)
self.assertEquals(graph.density(), float(1)/90)
graph.addEdge(0, 2)
self.assertEquals(graph.density(), float(2)/90)
#Test a graph with 1 vertex
graph = DictGraph(True)
graph.setVertex(0, 12)
self.assertEquals(graph.density(), 0)
graph.addEdge(0, 0)
self.assertEquals(graph.density(), 1)
