Value Function Iteration Well known, basic algorithm of dynamic programming. In linear value function approximation, the value function is represented as a linear combination of nonlinear basis functions (vectors). By (22) and condition (10), there exists a positive integer \(\bar{n}_{N-1}\) such that \(\tilde{J}^{o}_{N-1}\) is concave for \(n_{N-1}\geq\bar{n}_{N-1}\). CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The success of reinforcement learning in practical problems depends on the ability tocombine function approximation with temporal difference methods such as value iteration. By the implicit function theorem we get. Methods 24, 23–44 (2003), Semmler, W., Sieveking, M.: Critical debt and debt dynamics.
