A Method for Solving Special Circulant Pentadiagonal Linear Systems
A new effective modification of the method which is described in [1] for solving of real symmetric circulant pentadiagonal systems of linear equations is proposed. We consider t...

Q-learning and enhanced policy iteration in discounted dynamic programming
We consider the classical finite-state discounted Markovian decision problem, and we introduce a new policy iteration-like algorithm for finding the optimal state costs or Q-facto...
