The paper focuses on the study of the contradiction between two Atanassov's intuition-istic fuzzy sets. First, taking into account some characterizations obtained in previous papers, some functions are defined in order to measure the degrees of contradiction. Besides the principal properties of these measures are pointed out. Finally, some results relating(More)

GRAPHs is a new environment designed for active and independent simulation-based learning of graph algorithms. Apart from the options of creating and editing the graph and visualizing the changes made to the graph during simulation, the environment also includes step-by-step correction, algorithm animation, pop-up questions, data structure handling and(More)
In a previous paper, 1 we proposed an axiomatic model for measuring self-contradiction in the framework of Atanassov fuzzy sets. This way, contradiction measures that are semicontinuous and completely semicontinuous, from both below and above, were defined. Although some examples were given, the problem of finding families of functions satisfying the(More)
E-learning systems output a huge quantity of data on a learning process. However, it takes a lot of specialist human resources to manually process these data and generate an assessment report. Additionally, for formative assessment, the report should state the attainment level of the learning goals defined by the instructor. This paper describes the use of(More)
In this poster, some tools for graph algorithms active learning are presented. These tools pursue a new goal on computer assisted educational resources, so as to acting as authentic virtual trainers extending teacher's hand through the Web. In other words, they are on line self assessment tools that help students to execute the algorithms by themselves,(More)
