Specifies if a presolve must be done before solving.
void set_do_presolve(lprec *lp, short do_presolve);
set_do_presolve has no return value.
TRUE or FALSE. Do presolve or not.
The set_do_presolve function specifies if a presolve must be done before
solving. Presolve looks at the model and tries to simplify it so that solving
times are shorter. For example a constraint on only one variable is converted
to a bound on this variable (and the constraint is deleted). Note that the
model dimensions can change because of this, so be careful with this. Both
rows and columns can be deleted by the presolve.
