Function Utils::addSparseConstraints

Function Documentation

void Utils::addSparseConstraints(const arma::sp_mat &A, const arma::vec &b, GRBVar *x, const std::string &basename, GRBModel *model, int sense, GRBVar *z)

Create constraints for a given model given the matrix A, the RHS vector b, the variables x, and an additional RHS of variables z. The resulting constraints read: \(Ax \quad (sense) \quad b+z\)

Parameters

  • A – The input sparse matrix of LHS

  • b – The input vector of RHS

  • x – The input variables

  • basename – The basename of these constraints

  • model – A pointer to the model

  • sense – As in Gurobi.

  • z – Additional RHS of variables
