Opta Planner How could I arrange courses with combined classes

I am new to OptaPlanner. I am developing an Time table for a school using optaplanner. Optaplanner met most of the requirements I would like to have one additional requirement.
The requirement is two courses taught by the the same teacher should be given the same periord.

Teacher 1 teaches ENGLISH for curriculum 1 and 2. So whenever ENGLISH is taught in curriculum 1 it has to be assigned in curriculum 2 (same period and room). both curriculum 1 and 2 would share the same room (combined Class)

  Period    curriculum 1        curriculum 2           curriculum 3

Solution

  • In the example, one Course.java can have multiple curriculum (it has a curriculumList). So this constraint is already in there.
