A�liv pou�it�ynamick� programov� p����ok v ��lohy du�� ��analytick�e�en�bvykle nen�o�n��at. V ka�d��ov�kroku se toti� pot�se dv� obecn�bt��obl�my: 1) v� st� hodnoty a 2) minimalizace vzhledem k $u_t$. Oba probl� obecn�emaj�nalytick�e�en� bez dal��pecifikace � je proto t�p� k aproxima�m metod�

V t� kapitole p��me popis n�lika mo�n��up�proximativn� ��lohy du�� ��P�e� �e �u du�� ��je nalezen��c�trategie $\pi=\mu_{0:N-1}$, kter�y minimalizovala o��nou ztr�

J_\pi=\E_{y_0,w_{0:N-1}}\left\{g_N(y_N)+\sum_{t=0}^{N-1}g_t(y_t,\mu_t(I_t),w_t)\right\},
