The work presented in this paper is concerned with the development of a computational basis for the creation of constructivist learning environments capable of evaluating the process of interaction between the learner and the environment and promoting effective individualised learning based on these evaluations. Central to our approach is the formalisation of the process of learner-environment ...

Symbolic decision trees are not the only way to correlate the relationship between flags and numeric variables. Boolean formulae can also represent such relationships where the integer variables are modelled with bit-vectors of propositional variables. Boolean formula can be composed to express the semantics of a block and program state, but they are hardly tractable, hence the need to compute ...

abstract: the purpose of this study is to investigate the relationship between socialization and gender identity between female students from the university of dezful payme noor. the methodology of this study was survey and used a questionnaire. population of this study was all female students at dezful payme noor university and 384 persons determined as the sample size with using lin table. th...

The present review is based on the thesis that mate choice results from information-processing mechanisms governed by computational rules and that, to understand how females choose their mates, we should identify which are the sources of information and how they are used to make decisions. We describe mate choice as a three-step computational process and for each step we present theories and re...

E-mail address: [email protected] Goal programming (GP) has been, and still is, the most widely used technique for solving multiple-criteria decision problems and multiple-objective decision problems by finding a set of satisfying solutions. However, the major limitation of goal progr...

The associations between fertility and outcomes in the family and society have been treated as causal, but this is inaccurate if fertility is a choice coordinated by families with other life-cycle decisions, including labour supply of mothers and children, child human capital, and savings. Estimating how exogenous changes in fertility that are uncorrelated with preferences or constraints affect...

Cristiano Castelfranchi and Rino Falcone introduced an influential cognitive theory of social trust that is based on the concepts of belief, goal, ability, willingness and opportunity. In this paper we propose a simple logic of belief and action that allows to express these concepts. While our logic of belief is standard, our logic of action has a very simple kind actions: actions setting the t...

When considering problems of sequential decision making under uncertainty, two of the most interesting questions are: How does the value of the optimal decision variable change with an increase in risk? How does the value of the optimal decision variable change with a more informative signal? In this paper we show that, if the payoff function is linear in the random variable, then one model can...

The information systems with incomplete attribute values and fuzzy decisions commonly exist in practical problems. On the base of the notion of variable precision rough set model for incomplete information system and the rough set model for incomplete and fuzzy decision information system, the variable rough set model for incomplete and fuzzy decision information system is constructed, which is...
