Résumé

Based on the theory of adjoint equations, iterative algorithms for solving one class of problems of assimilating data for the reconstruction of the initial condition are developed and substantiated. The iterative processes are optimized with the use of the spectral properties of control operators. The results are illustrated by the example of the quasi-local model of turbulent heat transfer in the ocean.
