Fix a Chern character $v$ with positive rank, $\Delta(v) \geq 0$,
and $\beta_{-}(v) \in \QQ$.
The goal is to find all Chern characters $u=(r,c\ell,d\ell^2)$ which satisfy the

The values in the range can be tested individually, to check that
the rest of the conditions are satisfied.
\subsection*{Limitations}
Goals:
\begin{itemize}
\item large rank forces mu to beta_{-}, so many vals of mu(E) checked
needlessly
\item noticeably slow (show benchmark)
\end{itemize}
The main downside of this algorithm is that many $r$,$c$ pairs which are tested
end up not yielding any solutions for the problem.
In fact, solutions $u$ to our problem with high rank must have $\mu(u)$ close to
