A basic task in preference reasoning is inferring a preference between a pair of outcomes (alternatives) from an input set of preference statements. This preference inference task for comparative preferences has been shown to be computationally very hard for the standard kind of inference. Recently, a new kind of preference inference has been developed, which is polynomial for relatively expres...

This chapter approaches the image retrieval system on the base of the colors of image. It creates fuzzy signature to describe the color of image on color space HSV and builds fuzzy Hamming distance (FHD) to evaluate the similarity between the images. In order to reduce the storage space and speed up the search of similar images, it aims to create S-tree to store fuzzy signature relies on FHD an...

This paper characterizes the expressive power of a subclass of first-order logical decision trees (FOLDTs) as a fragment of firstorder logic. Specifically, using safe FOLDTs one can express precisely the boolean combinations of safe existential sentences.

Facility Location Problems have a great significance for allocating resources efficiently in a network. The interaction mainly involves a price which depends on the distances between the objects and the order of significance of the objects(clients). The applications of such problems are immense in many application areas such as medical and transportation. In this project, we consider the p-medi...

Given a quasi-ordering of labels, a labelled ordered tree s is embedded with gaps in another tree t if there is an injection from the nodes of s into those of t that maps each edge in s to a unique disjoint path in t with greater-or-equivalent labels, and which preserves the order of children. We show that finite trees are well-quasiordered with respect to gap embedding when labels are taken fr...

Capacity of garden productions in Iran is such that is accounted as a country that produces thirteen garden products in the world but despite excellent condition in Iran for producing garden products, natural disasters damage production of fruits in the country therefore farmers incur a loss. Pistachio tree has been in danger of destruction and dryness. Thus, in order to reduce loss incurred on...
