1. What is Ramsey Number?

Ramsey number is math problem that finding the minimum number of vertices k = R(m,n) so that any undirected graph with k vertices always contains a clique of m or an independent set of m.

2. What is latest updates on R(5,5)?

R(5,5) is the next Ramsey number with m=n that is not totally solved yet. Here are the latest updates:

3. What's the idea of this project?

The time complexity is extremely huge to go through every single nonisomorphic graph with 43 vertices. Brendan McKay mentioned that it takes 10^60 years with a brute-force method. So we want to try another volunteer-computing approach. For each volunteer:

  1. Generate a random graph G with 43 vertices randomly;
  2. Find the maximum clique number m;
  3. Find the maximum independent set n;
  4. If m<5 and n<5, return the graph G.

Still the probablity of finding valid graph that prove R(5,5) ≠ 43 is extremely small, but from the perspective of volunteer-computing, it's much easier than the traversal of all graph networks.
