ModelEvaluator for forming adjoint sensitivity equations.
This class wraps a given ModelEvalutor encapsulating f(x_dot,x,p) and creates a new "residual" for the adjoint sensitivity equations: F(y) = d/dt( df/dx_dot^T*y ) - df/dx^T*y + dg/dx^T = 0 where y is the adjoint variable. Nominally y is a multi-vector belonging to the vector space of the residual f with number of columns equal to the dimension of g. To satisfy the model evaluator interface, y is converted to a product vector formed by its columns. This is the form of the adjoint equations suitable for computing pseudotransientsensitivities of a response function g(x(T),p) or adjoint sensitivities for a time-integrated response function int_0^T g(x(t),p).
To compute adjoint sensitivities, the equations f(x_dot,x,p) = 0 are integrated forward in time to some final time T, with the adjoint equations above integrated backward in time starting at T. Since the tempus integrator can only integrate forward in time, we define tau = T - t and transform the adjoint equations to: F(y) = d/dtau( df/dx_dot^T*y ) + df/dx^T*y - dg/dx^T = 0. The initial conditions for y are y(T) = 0. The sensitivity of g(T) is then int_0^T(dg/dp(T) - df/dp^T*y)dt + dx/dp(0)^T*df/dx_dot(0)^T*y(0) for transient adjoint sensitivites and is dg/dp(T) - df/dp^T*y for pseudotransient.
This model evaluator supports both implicit and explict forms of the governing equations. However it assumes df/dx_dot is constant with respect to x_dot, x, and t so that the adjoint equations become F(y) = df/dxdot^T*y_dot + df/dx^T*y - dg/dx^T = 0. Moving beyond this assumption will require modifications to the steppers in how they generate time-derivative terms.

Constructor.
t_final is the final integration time used to implement the time transformation described above. num_adjoint is the number of adjoint variables defining the number of columns in y, which is determined by the number of elements in the vector space for the response g. The optionally supplied parameter list supports the following options:
