Identification of the parameters of a convection diffusion system

Computational algorithms are proposed for the realization of gradient methods based on the solution of direct and conjugate problems in weak formulations for some complex inverse problems of the recovery of parameters of multicomponent parabolic distributed systems. The approach proposed makes it unnecessary to set up Lagrange functionals in explicit form and to use the Green function.
