求图的顶点连通度算法。方法就是先对源和汇做枚举,之后对每个枚举情况,把除去源汇两点的其余所有顶点看成是容量限制为1的点,求网络的最大流,就是此点对的顶点连通度,之后对枚举的所有点对找连通度最小的当成图的连通度。
带有顶点容量限制的最大流方法:将带容量限制的顶点u拆成两个点u 和u*,原顶点u的入边为u 的入边,原顶点u的出边为u*的出边,之后在u 和u*之间连接双向边,边的容量为顶点的容量限制。-plans for the vertex connectivity algorithms. First is the method of sources and sinks so enumerated, after the enumeration of each, two sources and sinks to remove all remaining vertices as capacity constraints to a point, seeking the largest network flow, this is the apex of connectivity, followed by enumeration of all points of connectivity for the smallest of the plan as connectivity. Vertex capacity constraints with the biggest flow method : with the capacity constraints of the vertex is split into two u u and u *, the original entry point u u edge of the income side, the original point out u * u edge of the edge out after the u and u * a two-way link between the edge, while the capacity for the top point of the capacity constraints.
