I just navigated to https://github.com/rigetti/grove/blob/master/docs/qaoa.rst to grok the QAOA module. The page displays a bunch of LaTeX or markup unrendered, so it's very hard to see what's intended. E.g.,
"can be written as follows: $$\sum_{e \in E} w_{e} \cdot \mathrm{Pr}(e \in \mathrm{cut}) = \frac{1}{2} \sum_{e \in E}w_{e}$$"
and
"interpolation between the two operators \begin{align} \hat{H}{\tau} = \tau\hat{H}{\mathrm{ref}} + (1 - \tau)\hat{H}_{\mathrm{MAXCUT}} \end{align} where (\tau) changes between 1 and 0. "
