IloCplex
public IloCplex::BasisStatus getBasisStatus(const IloIntVar var)
This method returns the basis status for the variable var.
public IloCplex::BasisStatus getBasisStatus(const IloNumVar var)
This method returns the basis status for the variable var.
public void getBasisStatuses(IloCplex::BasisStatusArray cstat,
const IloNumVarArray var,
IloCplex::BasisStatusArray rstat,
const IloConstraintArray con)
This method puts the basis status of each variable in var into the corresponding element
of the array cstat, and it puts the status of each row in con (an array of ranges or
constraints) into the corresponding element of the array rstat. Arrays rstat and
cstat are resized accordingly.
public void getBasisStatuses(IloCplex::BasisStatusArray stat,
const IloConstraintArray con)
This method puts the basis status of each constraint in con into the corresponding
element of the array stat. Array stat is resized accordingly.
public void getBasisStatuses(IloCplex::BasisStatusArray stat,
const IloNumVarArray var)
This method puts the basis status of each variable in var into the corresponding element
of the array stat. Array stat is resized accordingly.
public IloNum getBestObjValue()
This method returns a bound on the optimal solution value of the problem. When a
model has been solved to optimality, this value matches the optimal solution value. If a
MIP optimization is terminated before optimality has been proven, this value is
computed for a minimization (maximization) problem as the minimum (maximum)
objective function value of all remaining unexplored nodes.
public void getBoundSA(IloNumArray lblower,
IloNumArray lbupper,
IloNumArray ublower,
IloNumArray ubupper,
const IloNumVarArray vars)
For the given set of variables vars, bound sensitivity information is computed. When
the method returns, the element lblower[j] and lbupper[j] will contain the
lowest and highest value the lower bound of variable vars[j] can assume without
affecting the optimality of the solution. Likewise, ublower[j] and ubupper[j]
will contain the lowest and highest value the upper bound of variable vars[j] can
assume without affecting the optimality of the solution. The arrays lblower,
lbupper, ublower, and ubupper will be resized to the size of array vars. The
value 0 (zero) can be passed for any of the return arrays if the information is not desired.
