applies one round of presolving with the given presolving timing
This method will always be called with presoltiming fast first. It iterates over all presolvers, propagators, and constraint handlers and calls their presolving callbacks with timing fast. If enough reductions are found, it returns and the next presolving round will be started (again with timing fast). If the fast presolving does not find enough reductions, this methods calls itself recursively with presoltiming medium. Again, it calls the presolving callbacks of all presolvers, propagators, and constraint handlers with timing medium. If enough reductions are found, it returns and the next presolving round will be started (with timing fast). Otherwise, it is called recursively with presoltiming exhaustive. In exhaustive presolving, presolvers, propagators, and constraint handlers are called w.r.t. their priority, but this time, we stop as soon as enough reductions were found and do not necessarily call all presolving methods. If we stop, we return and another presolving round is started with timing fast.

frees solution process data structures when reoptimization is used
in contrast to a freeSolve() this method will preserve the transformed problem such that another presolving round after changing the problem (modifying the objective function) is not necessary.

calculates a partition of the given set of binary variables into cliques; afterwards the output array contains one value for each variable, such that two variables got the same value iff they were assigned to the same clique; the first variable is always assigned to clique 0, and a variable can only be assigned to clique i if at least one of the preceding variables was assigned to clique i-1; for each clique at most 1 variables can be set to TRUE in a feasible solution;
scip is in one of the following stages:
| scip | SCIP data structure |
| vars | binary variables in the clique from which at most one can be set to 1 |
| values | clique value (TRUE or FALSE) for each variable in the clique |
