During the algorithm, hard constraints may be relaxed to soft constraints and given this weight. Therefore, if the problem contains hard constraints it is important to set this value larger than the largest weight of all the soft constraints.

Try setting this to true for better performance on instances with long planning horizons and/or many shift types and/or many employees.

Recommended value is between 2-3.

The maximum depth to allow the variable depth search to go to. Recommended value is between 300-500.

The maximum number of iterations of the main loop. Set as less than zero for not limit (default).

Recommended value is between 5-7.

Recommend setting this as Low or Medium. Set as Low if the Phase 2 construction heuristics are too slow. Setting it as High can increase performance on some instances but may be very slow on some instances. It is recommended to not set it as Unlimited.

In milliseconds.

Recommend setting this as true as it is very useful for some instances.

This field is no longer used.

Uses the system time as the random seed if true.

If true then the search will finish when PreferredRunTime is reached. If false it will finish once a single iteration is completed. The time taken for a single iteration can vary significantly depending on the instance being solved.
