Member Function Documentation

void ifopt::ExConstraint::FillJacobianBlock ( std::string  var_set,
Jacobian jac_block 
) const
inlineoverridevirtual

Set individual Jacobians corresponding to each decision variable set.

Parameters
var_setSet of variables the current Jacobian block belongs to.
jac_blockColumns of the overall Jacobian affected by var_set.

A convenience function so the user does not have to worry about the ordering of variable sets. All that is required is that the user knows the internal ordering of variables in each individual set and provides the Jacobian of the constraints w.r.t. this set (starting at column 0). GetJacobian() then inserts these columns at the correct position in the overall Jacobian.

If the constraint doen't depend on a var_set, this function should simply do nothing.

Implements ifopt::ConstraintSet.

Definition at line 128 of file ex_problem.h.

VecBound ifopt::ExConstraint::GetBounds ( ) const
inlineoverridevirtual

Returns the "bounds" of this component.

  • For Variable these are the upper and lower variable bound.
  • For Constraint this represents the constraint bounds.
  • For Cost these done't exists (set to infinity).

Implements ifopt::Component.

Definition at line 116 of file ex_problem.h.

virtual VectorXd ifopt::ExConstraint::GetValues ( ) const
inlineoverridevirtual

Returns the "values" of whatever this component represents.

  • For Variable this represents the actual optimization values.
  • For Constraint this represents the constraint value g.
  • For Cost this represents the cost value.

Implements ifopt::Component.
