Solve time constraints

[fire]

Describe the proposed feature and how it helps to overcome a problem or limitation

Solve time constraints for a visual novel.

Other information about your context or usecase.

A visual novel needs to plan around events like in the test case of a concert.

If known, describe how your proposal will work, with code, pseudo-code, mock-ups, or diagrams

Implement time constraints.

Create a state variable whose value is an agenda of future events, and having actions that insert events into the agenda.

1. When objects of a resource type are created, relevant aspects of state are initialized by providing an optional
   second argument (also delimited by curly brackets and in the form of predicate = value). As new action tokens are
   inserted onto a resource timeline, the preconditions and effects of the corresponding actions will dictate how relevant
   aspects of state will change
2. A sync-constraints denotes that task1 must start immediately after task0 completes.
3. T-HTN borrows directly from PDDL 2.1, incorporating its :duration field and the temporal qualifiers (atstart, atend, overall) used in preconditions and effects into the action definition of HDDL.

For me I want to solve this problem here.

Everyday there are three possible choices, and certain days have certain events.

Some progress, but lost the monotonic time constraint. Need to debug.

We may be able to use https://github.com/cgg-bern/quadwild-bimdf 's bimdf backend to solve time constraints.
