Determine DR polynomial degree to enforce based on
the iteration number and/or the presence of first-stage
equality constraints that depend on the decision rule variables.
If there are first-stage equality constraints that depend
on the decision rule variables, such as equalities derived
from coefficient matching or discretization of state-variable
independent equalities, then the degree is set to
config.decision_rule_order.
Otherwise, the degree is set to:
0 if iteration number is 0
min(1, config.decision_rule_order) if iteration number
otherwise does not exceed number of effective
uncertain parameters
min(2, config.decision_rule_order) otherwise.
- Parameters:
master_data (MasterProblemData) – Master problem data.
- Returns:
DR order, or polynomial degree, to enforce.
- Return type:
int
