Member Function Documentation

◆ computeValues()

void corbo::MSDynamicsOnlyEdge::computeValues ( Eigen::Ref< Eigen::VectorXd > values )

inlineoverridevirtual

Compute function values.

Here, the actual cost/constraint function values are computed:

objective in non-least-squares form: e(x) (hereby, the actual cost is f(x) = e(x)^T e(x))
objective in least-squares form: f(x)
equality constraints: ceq(x) (in case constraints are satisfied: ceq(x) = 0)
inequality constraints: c(x) (in case constraints are satisfied: c(x) < 0)
Parameters

[in] values values should be stored here according to getDimension().

Implements corbo::Edge< VectorVertex, VectorVertex, VectorVertex >.

Definition at line 71 of file multiple_shooting_edges.h.

◆ getDimension()

int corbo::MSDynamicsOnlyEdge::getDimension ( ) const

inlineoverridevirtual

Get dimension of the edge (dimension of the cost-function/constraint value vector)

Implements corbo::Edge< VectorVertex, VectorVertex, VectorVertex >.

Definition at line 59 of file multiple_shooting_edges.h.

◆ isLeastSquaresForm()

bool corbo::MSDynamicsOnlyEdge::isLeastSquaresForm ( ) const

inlineoverridevirtual

Defines if the edge is formulated as Least-Squares form.

Least-squares cost terms are defined as $ f(x) = e(x)^T e(x) $ and the function values and Jacobian are computed for $ e(x) $ rather than for $ f(x) $ . Specialiezed least-squares solvers require the optimization problem to be defined in this particular form. Other solvers can automatically compute the square of least-squares edges if required. However, the other way round is more restrictive: general solvers might not cope with non-least-squares forms.

Note, in the LS-form case computeValues() computes e(x) and otherwise f(x).

Returns: true if the edge is given in LS-form

Reimplemented from corbo::BaseEdge.

◆ isLinear()

bool corbo::MSDynamicsOnlyEdge::isLinear ( ) const

inlineoverridevirtual
