The question, whether an optional set of routes can be represented as shortest paths, and if yes, then how, has been a rather scarcely investigated problem up until now. In turn, an algorithm that, given an arbitrary set of traffic engineered paths, can efficiently compute OSPF link weights as to map the given paths to shortest paths may be of huge importance in today’s IP networks, which still...

abstract atrak basin is an agricultural area in north khorasan province that the most farmers are using from groundwater resources for irrigation their crops. decreasing rainfall in recent years in this area, competition between urban, agriculture and industrial consumers has increased for water acquisition. in present study, game theory was applied for groundwater resources management of atrak...

Question answering systems rely on retrieval components to identify documents that contain an answer to a user’s question. The formulation of queries that are used for retrieving those documents has a strong impact on the effectiveness of the retrieval component. Here, we focus on predicting the importance of terms from the original question. We use model tree machine learning techniques in ord...

In this paper, we study group decision-making problems based on intuitionistic preference relations. By measuring the uncertain information of intuitionistic preference relations and the average similarity degree of one individual intuitionistic preference relation to the others, we propose a new approach to assess the relative importance weights of experts. The approach takes both the objectiv...

Two principal semantics have been assigned to the division of fuzzy relations. In the first one, the weights of the divisor are seen as thresholds and in the other, they act as grades of importance. This paper discusses a third approach in which the weights play the role of ideal values. In this context, the notion of a graded inclusion between (fuzzy) sets moves to that of a graded equality. I...

Weights of evidence model is used to predict occurrence of an event with known evidences in a study area where training data are available to estimate the relative importance of each evidence by statistical methods. It provides a quantitative method for integrating multiple sources of evidences. It avoids subjective choice of evidences and subjective estimation of weights for evidences with com...

We've so far been studying a specific representation of an arbitrary compact Lie group, the adjoint representation. The roots are the weights of this representation. We would now like to begin the study of arbitary representations and their weights. An arbitrary finite dimensionsional represesentation will have a direct sum decomposition V = α V α where the α are the weights of the representati...
