GRBModel::get()
Query the value(s) of a parameter or attribute. Use this method for parameters, for scalar model attributes, or for arrays of constraint or variable attributes.
double | get ( | GRB_DoubleParam | param ) |
Query the value of a double-valued parameter.
Arguments:
param: The parameter being queried.
Return value:
The current value of the requested parameter.
int | get ( | GRB_IntParam | param ) |
Query the value of an int-valued parameter.
Arguments:
param: The parameter being queried.
Return value:
The current value of the requested parameter.

Arguments:
attr: The attribute being queried.
vars: An array of variables whose attribute values are being queried.
count: The number of variable attributes to retrieve.
Return value:
The current values of the requested attribute for each input variable. Note that the result is heap-allocated, and must be returned to the heap by the user.

constrs: An array of quadratic constraints whose attribute values are being queried.
count: The number of quadratic constraint attributes to retrieve.
Return value:
The current values of the requested attribute for each input quadratic constraint. Note that the result is heap-allocated, and must be returned to the heap by the user.
