A mathematical model of the hypothalamic-pituitary-adrenal (HPA) axis of the human endocrine system is proposed. This new model provides an improvement over previous models by introducing two nonlinear factors with physiological relevance: 1) a limit to gland size; 2) rejection of negative hormone concentrations. The result is that the new model is by far(More)
Emerging technologies, such as intelligent agents, avatars, and distributed environments offer new opportunities for the improvement of business games used for training decision makers. The advent of these technologies also creates new challenges to game developers and training consultants. We investigate these opportunities and offer suggestions on how to(More)
The non-player characters (NPCs), i.e. the artificial characters that are not under direct control by the user, are essential part of many digital games. Achieving the realistic behavior by NPCs in digital sports games such as the simulated soccer is challenging. Here we limit our scope to the defensive situation, i.e. when the ball is controlled by the(More)
We show that all published visual data processing methods for the simulated robotic soccer so far were not utilizing all available information, because they were mainly based on heuristic considerations. On the other hand, we show that the improved accuracy could result in a significant score gain even for a reasonably good simulated team. Some researchers(More)
