DStart
Type: | double |
---|---|
Modifiable: | Yes |
The current simplex start vector. If you set DStart
values
for every linear constraint in the model and
PStart values for every
variable, then simplex will use those values to compute a warm start
basis. If you'd like to retract a previously specified start, set any
DStart
value to GRB_UNDEFINED
.
Note that any model modifications made after setting DStart
(adding variables or constraints, changing coefficients, etc.) will
discard the start. You should only set this attribute after you are
done modifying your model.
Only affects LP models; it will be ignored for QP, QCP, or MIP models.
