- A markov chain model in decision makingPublication . Voskoglou, Michael G.An absorbing Markov chain is introduced in order to give a mathematical formulation of the decision making process. Examples are also given to illustrate our results .
- The Process of Learning Mathematics: A Fuzzy set ApproachPublication . Voskoglou, Michael G.There are often situations in real life in which definitions do not have clear boundaries; for example this happens when we speak about the "long rivers" or "high mountains" of a country, about the "young people" of a town, about the "tall pupils" of a school, e.t.c.. The fuzzy sets theory was created in response to the need to have a mathematical representation of such kind of situations. Let U denote the universal set of the discourse. Then a fuzzy set A in U, initiated by Zadeh [7], is defined by means of the membership function mA, which assigns to each element of U a real value from the interval [0,1]. More specifically A = {(x,mA(x)) : x Є U} , where mA U ----> [0,1).
