27  * @brief presolver that converts integer variables with domain [a,a+1] to binaries
28  * @author Tobias Achterberg
29  *
30  * This presolver converts all integer variables with domain \f$[a,a+1]\f$ to binaries variables. This is done by
31  * creating a new binary variable \f$y\f$ which will be aggregated to the old variable \f$x\f$ such that
32  * \f[
33  * x = y + a
34  * \f]
