An exact value for the Ramsey number $R (K_{5}, K_{5 - e})$

Vigleik Angeltveit

We compute the exact value of the Ramsey number $R (K_{5}, K_{5 - e})$ . It is equal to 30.

An improved algorithm for checking the Collatz conjecture for all n < 2^N

Vigleik Angeltveit

We describe a new algorithm for verifying the Collatz conjecture for all n < 2^N for some fixed N. The algorithm takes less than twice as long to verify convergence for all n < 2^{…
