XpressProblem.BranchObject

  • All Implemented Interfaces:
    java.lang.AutoCloseable
    Enclosing class:
    XpressProblem 
    public static class XpressProblem.BranchObject
extends XPRSbranchobject
    Subclass of XPRSbranchobject that allows using Variable instances to specify bounds and constraints. Instances of this class always expects bounds and expressions to be specified in terms of the original space (not presolved space).

      • addBounds

        public void addBounds​(int branch,
                      int nbounds,
                      byte[] bndtype,
                      Variable[] variables,
                      double[] bndval)
        Add bounds to this branching object. The function takes three parallel arrays ( bndtype, variables, bndval) that specify the bounds to be added. Each of these arrays must be of length at least nbounds and for each i in [0,nbounds[ the bound variable[i] bndtype[i] bndval[i] is added.

        Used in these examples:

        • MostViolated
        Parameters:
        branch - The branch on which bounds are added.
        nbounds - Number of bounds to add.
        bndtype - Bound types: 'L' for lower, or 'U' for upper
        variables - Variables on which bounds are added.
        bndval - Actual bounds for the variables.
        Since:
        43.00

      • addBound

        public void addBound​(int branch,
                     byte bndtype,
                     Variable variable,
                     double bndval)
        Add a single bound to this branch object.
        Parameters:
        branch - The branch on which the bound is added
        bndtype - Bound type: 'L' for lower, 'U' for upper.
        variable - The variable on which the bound is added.
        bndval - The bound on variable.
        Since:

      • addConstraint

        public void addConstraint​(int branch,
                          Inequality.Definition constraint)
        Add a row/cut to this branch object.
        Parameters:
        branch - The branch on which the row is added.
        constraint - The constraint to add.
