Task.chgbound()
Task.chgbound(
accmode,
i,
lower,
finite,
value)
Changes the bounds for one constraint or variable.
Arguments
accmode : accmode
Defines if operations are performed row-wise (constraint-oriented) or column-wise (variableoriented).
finite : int
If non-zero, then value is assumed to be finite.
i : int
Index of the constraint or variable for which the bounds should be changed.
lower : int
If non-zero, then the lower bound is changed, otherwise the upper bound is changed.
value : double
New value for the bound.
Description:
See also
Changes a bound for one constraint or variable. If accmode equals accmode.con, a constraint
bound is changed, otherwise a variable bound is changed.
If lower is non-zero, then the lower bound is changed as follows:
Otherwise if lower is zero, then
{ − ∞, finite = 0,
new lower bound =
value otherwise.
{
∞, finite = 0,
new upper bound =
value otherwise.
Please note that this function automatically updates the bound key for bound, in particular, if
the lower and upper bounds are identical, the bound key is changed to fixed.
• Task.putbound Changes the bound for either one constraint or one variable.
