setColsBndsGLPK function

Set/Change Column Bounds

This is an advanced version of setColBndGLPK. Here, j can be an integer vector, lb and ub

can be numeric vectors.

setColsBndsGLPK(lp, j, lb, ub, type = NULL)

Arguments

• lp: An object of class "glpkPtr" as returned by initProbGLPK. This is basically a pointer to a GLPK problem object.
• j: Vector of column numbers.
• lb: Vector of lower bounds.
• ub: Vector of upper bounds.
• type: Vector of variable types (default: NULL). For possible values, see glpkConstants, section LP/MIP problem object .

Details

Interface to the C function setColsBnds which calls the GLPK function glp_set_col_bnds.

If type is set to NULL, the type of the variables will be estimated. If lb[i] equals ub[i], variable j[i] is fixed, otherwise double bounded.

Returns

NULL
