Given the solution x of a discretized PDE or some other set of M equations parameterized by P variables p (design parameters, a.k.a. control variables or decision parameters), we often wish to compute some function g (x,p) based on the parameters and the solution. For example, if the PDE is a wave equation ... WebAccording to the adjoint method described in the paper, we then need to solve for the adjoint: a ( t) = ∂ L / ∂ z ( t). We do this by solving the differential equation which a satisfies: d a d t = − a ∂ f / ∂ z. we can do this and obtain. a ( t) = e α ( t − t 1) ( z ( t 1) − 1) Which we can easily see matches our boundary ... shona blackthorn
