Question: Will the optional apply when used with logic operators?

[dreinon]

I'm using the following structure:

for i in range(num_practices_double):
        practice_num += 1
        students_tasks.append(ps.FixedDurationTask(f'{stud_id}__{practice_num}', duration=2, priority = (21 - i),optional=True))
        students_tasks[-1].add_required_resource(Car)
        av_list = []
        for j in availability:
            av_list.append(ps.and_([ps.TaskStartAfterLax(students_tasks[-1], j[0],optional=True), ps.TaskEndBeforeLax(students_tasks[-1], j[1],optional=True)]))
        constraints.append(ps.ForceApplyNOptionalConstraints(av_list,1))

What I want to be optional is the constraint made by the and operator, I mean, the options would be, for example:

• Start at n1 AND end at n2
• Start at n3 AND and at n6

So I imagine something like ps.and_(logic, optional=true).

Thank you again :)
