We review some logic formalisms which were designed in order to reason about situations, goals, and actions. In particular, we focuss on the so-called frame problem, ie. the technical problem of how to formalize the assumption that unless an action explicitly causes a certain fact to hold or not to hold, the facts are preserved by the action. It is shown that there is no need to explicitly stat...

Here we present the implementation of an application capable of planning the shortest delivery route in the city of Medellín, Colombia. We discuss the different approaches to this problem which is similar to the famous Traveling Salesman Problem (TSP), but differs in the fact that, in our problem, we can visit each place (or vertex) more than once. Solving this problem is important since it wou...

Why do some children have difficulty in reading and others do not? We know that good readers use more effective strategies than poor readers . We also know that many problems can arise in the strategic processing of texts . Some students might not possess the necessary background or strategies for solving problems . Or, if they do, they might not understand when to employ the strategy that lead...

New technology is making it possible to replace professions built on complex knowledge, e.g. medicine. In our exploratory research we examined how Information Technologies might be replacing some of the tasks formerly processed by physician anesthesiologists (MDAs). Data (N=1178) were collected at a specialized hospital in the Netherlands. We observed the tasks carried out by fourteen MDAs duri...

Path planning is the key task in the field of Robotics. The modelling environment and algorithm to find shortest, collision free path are the basic issues in the path planning problem of the robot motion planning. This paper presents a literature review of different path planning techniques in static as well as dynamic environment. Planning a path in static environment is easy as compared to dy...

Case oriented tutoring gives students the possibility to practice their acquired theoretical knowledge in the context of concrete cases. Accordingly, tutoring systems for individualized learning have to take the skills of students at applying their knowledge to problem solving into account. This paper describes a case-based methodology for planning tutoring processes depending on the skills of ...

Although many have proposed formal characterizations of belief structures as bases for rational action, the problem of characterizing rational desires has attracted little attention. AI relies heavily on goal conditions interpreted (apparently) as absolute expressions of desirability, but these cannot express varying degrees of goal satisfaction or preferences among alternative goals. Our previ...

Advances in information technology and telecommunications, together with ever growing amounts of data, offer opportunities for transportation companies to improve the quality of the service that they provide to their customers. This paper explores this issue in the context of a dynamic and stochastic routing problem in which a single, uncapacitated vehicle serves a set of known customers locati...
