Detailed Description

The piecewise constant function must be below the given capacity. The initial function value is zero. Note that a negative capacity will thus be trivially infeasible.

Note

we take for the definition of the function at time t to be the sum of all delta with time <= t. But because we check for the capacity over the full horizon, we could have taken < t with no behavior change.

Member Function Documentation

Propagate()

bool operations_research::sat::ReservoirTimeTabling::Propagate ( )

finalvirtual

This will be called after one or more literals that are watched by this propagator changed. It will also always be called on the first propagation cycle after registration.

For positive delta_min, we can maybe increase the min.

For negative delta_min, we can maybe decrease the max.
