 made in the presentation to concentrate on the case we are interested in:
 Problem \ref{problem:problem-statement-2}, finding all pseudo-walls when
 $\beta_{-}(v)\in\QQ$ for a $v$ with positive rank.

+In the next Section \ref{sect:prob2-algorithm} from the previous chapter,
 a different algorithm will be presented making use of theorems from Section
 \ref{sec:refinement}
 with the goal of cutting down the run time.
