The weighted matroid parity problems for the matching matroid and gammoids are among the very few cases for which the weighted matroid parity problem is polynomial time solvable. In this work we extend these problems to a general revenue function for each pair, and show that the resulting problem is still solvable in polynomial time via a standard weighted matching algorithm. We show that in ma...

Agricultural droughts are droughts that affect the crop production or the ecology of a region. Ravar city that is located in margin of desert and the north of Kerman province is one of these areas. Due to the existence of enough underground water that entrance to desert and high evaporation to improving agricultural and cultivar activities, it needed to study the construction of underground dam...

Informatics and AI claim that the word is made of objects organized into classes (taxonomies, ontologies,...). In this paper, we explore an other idea: we structure our material relationships by collecting objects within collections, which are never as static as classes.

Given a set of points P in the plane and profits (or prizes) π : P → R≥0 we want to select a maximum profit set X ⊆ P which maximizes P p∈X π(p) − μ(X) for some particular criterion μ(X). In this paper we consider four such criteria, namely the perimeter and the area of the smallest axis-parallel rectangle containing X, and the perimeter and the area of the convex hull conv(X) of X. Our key res...

While highly effective, psychotherapy outcome studies suggest 5-14% of clients worsen while in treatment and that therapists are unable to identify a substantial portion of such cases. Methods to systematically collect feedback from psychotherapy clients are discussed and two systems for monitoring treatment response, feeding back this information, and assisting in problem-solving with such cas...
