WebThe solution for the path graph with only node 0 is the independent set 0 with weight 6. The solution for the path graph with nodes 0 and 1 can only have one node (it has to be an independent set!). So, it will pick node 0 or node 1, the one with highest weight. In our case the solution is 1 with weight 10. Webgraph of a set S of convex 2D objects. If κ is the size of the maximum independent set of this graph, their algorithm returns an independent set of size (κ/(2log(2n/κ)))13 in O(n3 +τ(S)) time, where τ(S) is the time necessary to compute the left- and rightmost point of each object and test which objects intersect.
