Fuzzy cognitive maps are signed directed graphs used to model the evolution of scenarios with time. FCMs can be useful in decision support for predicting future states given an initial state. Genetic algorithms (GA) are well-established tools for optimization. This paper concerns the use of FCMs in goal-directed analysis of scenarios for aiding decision making. A methodology for GA-based goal-directed analysis is presented. The search for the initial stimulus state, that over time leads to a target state of interest, is optimized using GA. This initial state found can be used to answer the question – what course of events leads to a certain state in a given scenario?

Telepresence is constituted of a robotic system controlled by a human operator at a remote control station. In these systems the human operator is immerse in a virtual reality and the robot is controlled at distance by human operator. Often the human operator has that repeat tasks through robot. In this article we propose that the telepresence can use semi-autonomous (semi-reactive) robots, that execute the tasks that the operator repeats often, However, to create a relationship between the human operator and the semi-autonomous (semi-reactive) robot, it is necessary to develop a logic that combines the knowledge of the reactive robot and the knowledge of the human operator. On the other hand, in the last years we have seen the possibility to structure virtual worlds with Fuzzy Cognitive Maps. These maps can model virtual worlds with numerous actors. Moreover these FCMs can combine different virtual worlds. In this article we introduce a multi-agent modal logic of knowledge and belief that can be used in design of telep resence with semi-reactive robots. In this logic we describe possible worlds (“states of nature”) by fuzzy cognitive maps.
