| Method |
AddLinearConstraint | Return type: int Arguments:
int64_t lower_bound, int64_t upper_bound,
const std::vector<std::pair<int, double>>& variable_coeffs Adds a linear constraint, enforcing
lower_bound <= sum variable * coeff <= upper_bound,
and returns the identifier of that constraint.
|
AddMaximumConstraint | Return type: virtual void Arguments: int max_var, std::vector<int> vars |
AddObjectiveConstraint | Return type: virtual void |
AddProductConstraint | Return type: virtual void Arguments: int product_var, std::vector<int> vars |
AddReifiedLinearConstraint | Return type: int Arguments:
int64_t lower_bound, int64_t upper_bound,
const std::vector<std::pair<int, double>>& weighted_variables Adds a linear constraint and a 0/1 variable that is true iff
lower_bound <= sum variable * coeff <= upper_bound,
and returns the identifier of that variable.
|
AddVariable | Return type: int Arguments: int64_t lower_bound, int64_t upper_bound Adds a variable with bounds [lower_bound, upper_bound].
