On some small classical Ramsey numbers
Summary: This note is a report on a computer investigation of some small classical Ramsey numbers. We establish new lower bounds for the classical Ramsey numbers \(R(3,11)\) and \(R(4,8)\). In the first case, the bound is improved from 46 (a record that had stood for 46 years) to 47; and in the second case the bound is improved from 57 to 58.
