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.

Current roadmap of Ramsey Numbers on Wolfram: https://mathworld.wolfram.com/RamseyNumber.html

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

• In 1989, Geoffrey Exoo found the lower bound of R(5,5)>=43 at 1989.
• In 2019, Vigleik Angeltveit and Brendan D. Mckay found the upper bound of R(5,5)<=48 at https://arxiv.org/pdf/1703.08768.pdf.
• The latest update about upper bound of Ramsy number is from Ashwin Sah at https://arxiv.org/pdf/2005.09251.pdf.

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.
