This research studies the generation gap among the students at Andimeshk Islamic Azad University. More than 305 people were chosen by Cochran Formula in the study. The dependent variable was divided to four dimensions social, cultural, political and economic. The obtained mean of the study shows there is a meaningful difference between students and their parents (fathers and mothers). It also s...

This paper reconsiders the problems of discovering symmetries in constraint satisfaction problems (CSPs). It proposes a compositional approach which derives symmetries of the applications from primitive constraints. Its key insight is the recognition of the special role of global constraints in symmetry detection. Once the symmetries of global constraints are available, it often becomes much ea...

We prove that when a digraph G has a Maltsev polymorphism, then G also has a ma jority polymorphism. We consider the consequences of this result for the structure of Maltsev digraphs and the complexity of the Constraint Satisfaction Problem.

The structural rigidity property, a generalization of Laman's theorem which characterizes rigid bar frameworks in 2D, is generally considered a good heuristic to detect rigidities in a geometric constraint satisfaction problem (GCSP). The gap between rigidity and structural rigidity essentially resides in the fact that structural rigidity is not a geometric property. In this article, we propose...

In the frame of classical Constraint Satisfaction Problems (CSPs), the backtrack tree search, combined with learning methods, presents a double advantage : for static solving, it improves the search speed by avoiding redundant explorations; for dynamic solving (after a slight change of the problem), it reuses the previous searches to build a new solution quickly. Backtrack reasoning concludes t...

Constraint satisfaction networks contain nodes that receive weighted evidence from external sources and/or other nodes. A relaxation process allows the activation of nodes to affect neighboring nodes, which in turn can affect their neighbors, allowing information to travel through a network. When doing discrete updates (as in a software implementation of a relaxation network), a goal net or goa...

Comparative preference statements are the basic ingredients of conditional logics for representing users’ preferences in a compact way. These statements may be strict or not and obey different semantics. Algorithms have been developed in the literature to compute a preference relation over outcomes given a set of comparative preference statements and one or several semantics. These algorithms a...

the relationship between curiosity and subjective well-being of married women: mediating effect of intimacy and marital satisfaction the purpose of present study was to investigate the relationship between curiosity and intimacy and marital satisfaction in married women's subjective well-being. for this purpose 265 married women in tehran were selected using voluntary sampling. research in...

price fairness and price satisfaction is one the most important fields in pricing and also in customer satisfaction. in this research, first the dimensions of price fairness, price satisfaction, customer satisfaction, and customer loyalty are extracted from marketing literature, then five hypotheses are developed. in proposed model, price fairness has direct impact on price satisfaction, custom...

background communication skills of operational managers such as head nurses greatly influence the performance of nursing personnel and by extension, the quality of the care provided by them. objectives this study was conducted to identify the role of a development program on communication skills and job satisfaction in head nurses. materials and methods this research was a non-randomized two-gr...
