The second step is to invoke the naive colouring procedure and the probabilistic method to colour the graph. Indeed, using these techniques, it can be shown that a δ-sparse graph is (1 − ε) (Δ (G) + 1)-colourable for some ε > 0 depending on δ. This completes the proof.

We consider the maximum independent set problem on sparse graphs with maximum degree d. We show that the Lovász ϑ -function based semidefinite program (SDP) has an integrality gap of O ~ ( d / log 3 / 2 d), improving on the previous best result of O ~ ( d / log d). This improvement is based on a new Ramsey-theoretic bound on the ... gilded shadows guideWebAug 23, 2024 · Step 1 − Arrange the vertices of the graph in some order.
