Fields
|
|
------
|
|
|
|
- `time_limit`:
|
|
the time limit over the entire optimization procedure.
|
|
- `gap_limit`:
|
|
the desired relative optimality gap. Only used when `two_phase_gap=true`.
|
|
- `two_phase_gap`:
|
|
if true, solve the problem with large gap tolerance first, then reduce
|
|
the gap tolerance when no further violated constraints are found.
|
|
- `max_violations_per_line`:
|
|
maximum number of violated transmission constraints to add to the
|
|
formulation per transmission line.
|
|
- `max_violations_per_period`:
|
|
maximum number of violated transmission constraints to add to the
|
|
formulation per time period.
