This method will be called at the start of the search.
It asks the decision builder if it wants to append search monitors to the list of active monitors for this search. Please note there are no checks at this point for duplication.

Reimplemented from BaseObject.
Reimplemented in IntVarFilteredDecisionBuilder, and FindOneNeighbor.
Definition at line 2527 of file constraint_solver.cc.
This is the main method of the decision builder class.
It must return a decision (an instance of the class Decision). If it returns nullptr, this means that the decision builder has finished its work.
Implemented in IntVarFilteredDecisionBuilder, SweepBuilder, and FindOneNeighbor.
