Simple parallel response-only ModelEvaluator.
The representation of the model in coefficient form is:
Public Types inherited from g(p) = 0.5 * sum( diag[i] * (p[i] - ps[i])^2, i=0...n-1 )
+ 0.5 * nonlinearTermFactor * sum( (p[i] - ps[i])^3, i=0...n-1 )
+ g_offsetIn vector coefficient form it becomes:
g(p) = 0.5 * (p-ps)^T * D * (p-ps) + cubicTerm(p) + g_offset
where D = diag(diag) and cubitTerm(p) is given above.
This test model implementation also supports the definition of diagonal scalar product implementation. The impact of this is the definition of new abstract Thyra Euclidean vectors of the form:
p_bar = E_p * p g_grad_bar = E_p * g_grad
In this notation, we say that the Thyra vectors themselves p_bar are vectors in a Euclidean space (from the standpoint of the ANA clients) and that p are the coefficient vectors in the new non-Euclidean space S_p with scalar product:
y_bar^T * x_bar = y^T * E_p^T * E_p * x
= y^T * S_p * x
= <y, x>_pThe ideas is that by providing this new vector space basis E_p and inner product <.,.>_p, we change the function that the ANA sees.
This testing class allows a client to specify the desirable diagonal D_bar matrix by passing in the vector diag_bar. From diag_bar and diag, the diagonal s_diag for S_p = diag(s_diag) as:
s_diag[i] = diag_bar[i] / diag[i]
The inner product is therefore:
scalarProd(y_bar, x_bar) = sum( s_diag[i] * y[i] * x[i], i=0...n-1 )
