Description

constraint is an S4 class to represent a single constraint.

Slots

constraint

the numeric index of the constraint.

constraint_id

the character ID of the constraint.

nc

the number of MIP-format constraints translated from this constraint.

mat,dir,rhs

these represent MIP-format constraints. A single MIP-format constraint is associated with a row in mat, a value in rhs, and a value in dir.

• the i-th row of mat represents LHS coefficients to use on decision variables in the i-th MIP-format constraint.

• the i-th value of rhs represents RHS values to use in the i-th MIP-format constraint.

• the i-th value of dir represents the imposed constraint between LHS and RHS.

suspend

TRUE if the constraint is not to be imposed.
