Function Documentation

bool Utils::containsConstraint(const arma::sp_mat &A, const arma::vec &b, const arma::sp_mat &lhs, const double &rhs, const double tol = 1e-6)

Given a matrix A and a vector of LHSs b, checks if both lhs is in A, and rhs is in b up to a tolerance of tol.

Parameters

• A – The matrix containing the constraints

• b – The vector containing the RHSs

• lhs – The input cut RHS (in a matrix form)

• rhs – The input cut LHS

• tol – A numerical tolerance

Returns

True if the constraint was found
