It is hence not sufficient or advisable to limit the search to the set of active schedules.
Unfortunately, for scheduling problems with objective functions that combine regular and non-regular components, such as the RCPSP-ROC with revenues and overtime cost, it is not sufficient to only consider the set of active schedules, see Ballestin and Blanco (2015), p.
Current students and alumni of the Jazz Studies Department maintain very active schedules in both performance and education, working frequently in Maryland, Virginia, the District of Columbia, and New York, as well as internationally.
For scheduling problems with regular objective functions, e.g., makespan minimization, this is the set of so-called active schedules (mathcal {AS}).
Like the RCPSP, the problem is (mathcal {NP} -hard, but unlike the RCPSP, it turns out that an optimal schedule does not have to be among the set of so-called active schedules.
As a consequence, it is sufficient to consider "only" all active schedules to find the optimal solution.
Then, through a bi-level formulation, the active maintenance scheduling and operation is carried out with profit-maximization objective.
To convert the chromosome values to an active schedule, we used the priority-based decoding of Gao et al.
Secondly, the harmony vector is mapped into a feasible active schedule through effectively decoding the transformed two-vector code, which could largely reduce the search space.
He remains an influential figure in Israel and abroad, maintaining an active schedule through the Peres Center for Peace, a nonprofit organization that promotes reconciliation, tolerance and innovation.
While focusing on its role as a center for scholarly research in the history of art and museum training for graduate and undergraduate students at Yale, the gallery also maintains an active schedule of public education programming.
