Computational Bounds

Definition

Computational bounds refer to the limits or constraints on the performance and efficiency of algorithms used to calculate Ramsey numbers. These bounds are crucial in understanding the feasibility of determining exact Ramsey numbers and the resources required for such computations. They help researchers assess how close we can get to the actual Ramsey numbers without necessarily computing them directly, guiding both theoretical exploration and practical algorithm design.
