# counting problem

*counting problem*. Note that $c_{R}$ is a search problem while $\#R$ is a decision problem, however $c_{R}$ can be $\mathcal{C}$ Cook reduced to $\#R$ (for appropriate $\mathcal{C}$) using a binary search (the reason $\#R$ is defined the way it is, rather than being the graph of $c_{R}$, is to make this binary search possible).
