Inferences about the underlying system can only be made when a sufficient number of runs are performed to estimate the relevant metric within some confidence interval. This paper proposes a new algorithm for determining the minimum number of independent runs needed to make inferences about a GP system. As such, we view our algorithm as a meta-metric that should be satisfied before any inferences about a system are made. We call this metric COSMOS, as it estimates the number of independent runs needed to achieve the Convergence Of Sample Means Of the Order Statistics. It is agnostic to the underlying GP system and can be used to evaluate extant performance metrics, as well as problem difficulty. We suggest ways for which COSMOS may be used to identify problems for which GP may be uniquely qualified to solve.", notes = "Also known as \cite{2330848} Distributed at GECCO-2012.
