We discuss an analysis of Constraint Satisfaction problems, such as Sphere Packing, K-SAT and Graph Coloring, in terms of an effective energy landscape. Several intriguing geometrical properties of the solution space become in this light familiar in terms of the well-studied ones of rugged (glassy) energy landscapes. A ‘benchmark’ algorithm naturally suggested by this construction finds solutio...

Good heuristics have long been credited as some of the most important components of constraint satisfaction search algorithms. Understanding their behaviour has been the subject of a significant number of both theoretical and empirical research papers, yet from a practical standpoint, questions about certain important performance characteristics remained unanswered. For example, what is the sma...

In this paper we deal with the problem of identifying a valid way to characterize heterogeneity in the analysis of customer satisfaction observing the phenomenon through a new perspective. In the literature, the variability of a Customer Satisfaction index is measured by the standard deviation or the coefficient of variation. In this way, heterogeneity among customers may be masked. To overcome...

The Organic.Edunet Web portal is a multilingual federation of educational repositories, developed in order to enhance the availability and retrieval of quality educational resources about Organic Agriculture (OA) and Agroecology (AE). This paper presents the results of an online survey that took place from March to August 2010 in order to evaluate the user satisfaction from the Organic.Edunet W...

The aim of this paper is to investigate the determinants and consequences of customer satisfaction in hotel industry in Iran. A Confirmatory Factor Analysis (CFA) and Structural Equation Modeling have been utilized with information provided by a survey conducted in Iran (Kish Island).Results indicate that perceived value has a significant impact on customer satisfaction in hotel industry. Moreo...

A problem of identifying key drivers in customer satisfaction analysis is considered in relation to Kano theory on the relationship between product quality and customer satisfaction using tools from Cooperative Game Theory and Risk Analysis. We use Shapley Value and Attributable Risk techniques to identify priorities of key drivers of customer satisfaction, or key dissatisfiers and key enhancer...

Technology influences various things in people's lives, ranging from socialization to shopping behaviour, and hence marketplace inevitably appears as a part of e-commerce concepts. Opinions related activities are thus interesting for further research. This paper investigates the appropriate methods analyzing customer satisfaction. The research was conducted by compiling aspects satisfaction the...

Cross-group relationships are defined as romantic involving two individuals from distinct racial or ethnic groups. For this paper, the terms “interethnic” and “interracial” used specifiers for umbrella terms, “intergroup” “cross-group.” Previous studies that examined whether cross-group more less satisfying than intragroup (i.e., same-group) have yielded discrepant findings. Through a systemati...
