Detailed Description

A description of an optimal control problem, backed by OpenSim Models.

A MocoProblem is a series of phases, each of which contains the following:

  • OpenSim Model
  • state and control variable info (e.g., bounds)
  • parameter variables (model properties)
  • goals (costs and endpoint constraints)
  • path constraints

Currently, only single-phase problems are supported. This class has convenience methods to configure the first (0-th) phase.

This class allows you to define your problem, but does not let you do anything with your problem (this class only contains user input). Use createRep() to create an instance of MocoProblemRep, which provides additional functionality.

MocoGoalType* OpenSim::MocoProblem::addGoal ( std::unique_ptr< MocoGoalType >  goal)
inline

◆ addParameter() [1/2]

template<typename MocoParamType = MocoParameter, typename... Args>
MocoParamType* OpenSim::MocoProblem::addParameter ( Args &&...  args)
inline

inline

Add a parameter variable for phase 0.

◆ addPathConstraint() [1/2]

template<typename MocoPCType , typename... Args>
MocoPCType* OpenSim::MocoProblem::addPathConstraint ( Args &&...  args)
inline

Add a constraint for phase 0.

See also
MocoPhase::addPathConstraint()

◆ addPathConstraint() [2/2]

template<typename MocoPCType >
MocoPCType* OpenSim::MocoProblem::addPathConstraint ( std::unique_ptr< MocoPCType >  pc)
inline

Add a constraint for phase 0.

◆ clone()

MocoProblem* OpenSim::MocoProblem::clone ( ) const
inlineoverridevirtual

Create a new heap-allocated copy of the concrete object to which this Object refers.

It is up to the caller to delete the returned object when no longer needed. Every concrete object deriving from Object implements this pure virtual method automatically, via the declaration macro it invokes (e.g., OpenSim_DECLARE_CONCRETE_OBJECT()). Note that the concrete class overrides modify the return type to be a pointer to the concrete object; that still overrides the base class method because the return type is covariant with (that is, derives from) Object.

Implements OpenSim::Object.

◆ createRep()

MocoProblemRep OpenSim::MocoProblem::createRep ( ) const
inline

Create an instance of MocoProblemRep, which fills in additional state and control bounds, and allows you to apply parameter values and evaluate the goals.

This function will check your problem for various errors.

◆ createRepHeap()

std::unique_ptr<MocoProblemRep> OpenSim::MocoProblem::createRepHeap ( ) const
inline

Use this variant of createRep() if you require the MocoProblemRep to be dynamically-allocated MocoProblemRep.

◆ getClassName()

static const std::string& OpenSim::MocoProblem::getClassName ( )
inlinestatic

This returns "MocoProblem"

See getConcreteClassName() if you want the class name of the underlying concrete object instead.

◆ getConcreteClassName()

const std::string& OpenSim::MocoProblem::getConcreteClassName ( ) const
inlineoverridevirtual

Returns the class name of the concrete Object-derived class of the actual object referenced by this Object, as a string.

This is the string that is used as the tag for this concrete object in an XML file. Every concrete class derived from Object automatically overrides this method via the declaration macro it uses. See getClassName() to get the class name of the referencing (possibly abstract) class rather than the concrete object.

See also
getClassName()

Implements OpenSim::Object.

◆ getPhase()

const MocoPhase& OpenSim::MocoProblem::getPhase ( int  index = 0) const
inline

Get a modifiable phase of the problem by index (starting index of 0).

This accesses the internal phases property.

Find and print the names of all state variables containing a substring.

◆ safeDownCast()

static MocoProblem* OpenSim::MocoProblem::safeDownCast ( OpenSim::Object obj)
inlinestatic

For use in MATLAB and Python to access the concrete class.

Example: cObj = MocoProblem.safeDownCast(obj). This is equivalent to dynamic_cast<MocoProblem*>(obj) in C++.
