Intelligent Control of Traffic Lights
Skoták, Miloš ; Samek, Jan (referee) ; Malačka, Ondřej (advisor)
In this thesis is analyzed Multi-Agent system for intelligent control of traffic lights. For the simulation of a real situation was implemented a simulator of a traffic situation written in Java language, which is based on a cellular automata. In Multi-Agent system can be found not only communication between the agent and environment, but also communication among agents. To implement the rules was used extended AgentSpeak language model based on BSD with Jason interpreter. Experiments were done on a real road section in the city Brno.

Trust and Reputation in Distributed Systems
Malačka, Ondřej ; Samek, Jan (referee) ; Zbořil, František (advisor)
The goal of this master's thesis is to design and implement agent system for dealing with sportsmen. It will be possible to apply trust and reputation principles on this system. This system is implemented in Jason agent language. Agents there posing as sports club managers. The main target of these managers is to have the maximal profit. The environment of agents is changing by playing the matches between the teams. Players quality evalution follows the played matches. Based on played matches, managers can evaluate the worth of each player and trade them in order to achieve the maximal possible profit. Untrustworthy agents take a place in this system. These agents overvalue their players using inccorect behavior. The experiments will be made within this masters's thesis in order to compare gain of apllication trust and reputation principles.
