Detailed Description

template<typename PROBLEM, typename VECTOR>
class DOpE::Reduced_SnoptAlgorithm< PROBLEM, VECTOR >

This class provides a solver for constrained optimization problems in reduced form, i.e., the dependent variable given by an equality constraint is assumed to be eliminated by solving the equation. I.e., we solve the problem min j(q) s.t., a q b, g(q) 0

The solution is done by interfacing to the SNOPT library.

Template Parameters

<PROBLEM>	The problem container. See, e.g., OptProblemContainer
<VECTOR>	The vector type of the solution.

Member Function Documentation

template<typename PROBLEM , typename VECTOR >

void DOpE::Reduced_SnoptAlgorithm< PROBLEM, VECTOR >::declare_params ( ParameterReader &  param_reader )

static

Used to declare run time parameters. This is needed to declare all parameters a startup without the need for an object to be already declared.

template<typename PROBLEM , typename VECTOR >

int DOpE::Reduced_SnoptAlgorithm< PROBLEM, VECTOR >::Solve ( ControlVector< VECTOR > &  q, double  global_tol = -1.  )

virtual

This solves an Optimizationproblem in only the control variable using the commercial optimization library snopt. To use it you need to define the compiler flag WITH_SNOPT and ensure that all required snopt headers and libraries are within the path or otherwise known.

Parameters

q	The initial point.
global_tol	An optional parameter specifying the required tolerance. The actual tolerance is the maximum of this and the one specified in the param file. Its default value is negative, so that it has no influence if not specified.

Implements DOpE::ReducedAlgorithm< PROBLEM, VECTOR >.
