Detailed Description

template<class Scalar>
class Thyra::DefaultMultiPeriodModelEvaluator< Scalar >

Composite subclass that takes a single ModelEvaluator object and represents it as a single aggregate multi-period ModelEvalator object.

Mathematically, this subclass is used to form a multi-period (or multi-point) problem of the form:

   (x_bar,{p_l}\p_period) -> f_bar

   (x_bar,{p_l}\p_period) -> g_bar

where

   x_bar = [ x[0]; x[1]; ...; x[N-1]]

   {p_l}\p_period = { p_(0), p_(1), ..., p_(z_index-1), p_(z_index+1), ..., p_(Np-1) }

   f_bar(...) = [ f(x[0],{p_l},z[0]); f(x[1],{p_l},z[1]); ..., f(x[N-1],{p_l},z[N-1]) ]

   g_bar(...) = sum( g_weights[i]*g[g_index](x[0],{p_l},z[i]), i = 0,...,N-1 )

Above, the notation {p_l} is meant to represent the set of all parameter subvectors in each of the constituent models minus the parameter subvector used to define period data.

This gives the first derivative objects:

                      [ W[0], 0,     ...  0      ]
                      [ 0,    W[i],  ...  0      ]
   W_bar = DfDx_bar = [ .,    .,     ...  .      ]
                      [ 0,    0,     ...  W[N-1] ]

  
                 [ DfDp[0][l]   ]
                 [ DfDp[1][l]   ]
   DfDp_bar[l] = [ ...          ]
                 [ DfDp[N=1][l] ]


                  [ g_wieght[0] * DgDx_dot[0]     ]
                  [ g_wieght[1] * DgDx_dot[1]     ]
   DgDx_dot_bar = [ ...                           ]
                  [ g_wieght[N-1] * DgDx_dot[N-1] ]


              [ g_wieght[0] * DgDx[0]     ]
              [ g_wieght[1] * DgDx[1]     ]
   DgDx_bar = [ ...                       ]
              [ g_wieght[N-1] * DgDx[N-1] ]


   DgDp_bar = sum( g_weights[i]*DgDp[i][g_index], i = 0,...,N-1 )

This class could be made much more general but for now ???

Member Function Documentation

template<class Scalar>
void Thyra::DefaultMultiPeriodModelEvaluator< Scalar >::initialize ( const int  N,
const Array< RCP< ModelEvaluator< Scalar > > > &  periodModels,
const Array< int > &  z_indexes,
const Array< Array< RCP< const VectorBase< Scalar > > > > &  z,
const int  g_index,
const Array< Scalar >  g_weights,
const RCP< const ProductVectorSpaceBase< Scalar > > &  x_bar_space = Teuchos::null,
const RCP< const ProductVectorSpaceBase< Scalar > > &  f_bar_space = Teuchos::null,
const RCP< LinearOpWithSolveFactoryBase< Scalar > > &  W_bar_factory = Teuchos::null 
)

Initialize.

Parameters:
N [in] The number of periods.
periodModels [in] Array (length N) of the period models. For now, each of the period models at periodModels[i] must have an identical structure for every input and output. The reason that different models are passed in is so that different behaviors of the output functions and different nominal values for each period's x and bounds can be specified. The nominal values from periodModels[0] will be used to set the nominal values for the non-peroid parameters.
z_indexes [in] Array of sorted zero-based indexes of the model's parameter subvector that represents z[i]. Note, this array must be sorted from smallest to largets and can not have any duplicate entires!
z [in] Array (length N) of the period defining auxiliary paramter subvectors. Each entry z[i] is an array of subvectors where z[i][k] is the subvector p(z_indexes[k]) in the underlying perild model. Therefore, the array z[i] must be ordered according to z_indexes. Note that z[i][k] is allowed to be null in which case the underlying default value for this parameter will be used.
g_index [in] The index of the response function that will be used for the period objective function.
g_weights [in] Array (length N) of the g_weights for the auxiliary response functions in the summation for g_bar(...) shown above.
x_bar_space [in] The product vector space that represents the space for x_bar as defined above. If x_bar_space.get()==NULL then a default version of this product space will be created internally.
f_bar_space [in] The product vector space that represents the space for f_bar as defined above. If f_bar_space.get()==NULL then a default version of this product space will be created internally.
W_bar_factory [in] Factory object that is used to create the block LOWS object that will be used to represent the block diagonal object W_bar. If is_null(W_bar_factory)==true on input then a DefaultBlockedTriangularLinearOpWithSolveFactory object will be created and used internally.
