In this paper we develop a modern approach to solar cycle forecasting, based on the mathematical theory of nonlinear dynamics. We start from the design of a static curve fitting model for the experimental yearly sunspot number series, over a time

In this article we consider the approximate solution for semi-Markov decision problems with infinite horizon, countable state space, discounted cost function and finite action space. We present converging sequences of lower and upper bounds for the v

In this paper it is shown that a modified Gauss-Seidel-Algorithm with exclusion of suboptimai actions can be used for approximative solving a continuously discounted Semi-Markovian decision problem. Moreover it is proved that the overrelaxation facto

In this paper it is shown that successive overrelaxation can be used for approximative solving a continuously discounted Semi-Markovian decision problem. The overrelaxation factor yielding minimum contraction factor is determined. This factor is at m

In this note a semi-Markovian dynamic programming model with vector-valued rewards will be considered. For the sets of maximal n-step–rewards with respect to a convex cone recurrence set relations are proved. It is shown that this set relations are

The paper deals with vector-valued semi-Markovian decision process (VSMDP). Thereby we derive a suitable definition of the optimal average reward of a VSMDP. We construct an algorithm for improving policies in the vector-valued case.
