چکیده

Slope selection, i.e. selecting the slope with rank k among all ( n 2 ) lines induced by a collection P of points, results in a widely used robust estimator for linefitting. In this paper, we demonstrate that it is possible to perform slope selection in expected O(n·log2 n) time using only constant extra space in addition to the space needed for representing the input.

An Efficient Approximate Algorithm for the k-th Selection Problem

We present an efficient randomized algorithm for the approximate k-th selection problem. It works in-place and it is fast and easy to implement. The running time is linear in the length of the input. For a large input set the algorithm returns, with high probability, an element which is very close to the exact k-th element. The quality of the approximation is analyzed theoretically and experime...

Site selection of water storage based on multi-criteria decision analysis

Water loss can be minimized and conserve through constructing small storage dams for various irrigation purposes to support local livelihood. Geographic information system provides powerful techniques for many hydrological modeling and suitable dam site selection. The current study explored potential sites for small storage dams to meet agricultural requirements in district Malakand, Khyber Puk...

Deriving Economic Values for Reaction Norms of Growth in Pigs

Slopes of reaction norm models, also called reaction norms (RN), are alternative traits used in animal breeding for selection of genotypes that perform more consistently across a range of environments. Environmental sensitivity is of economic importance when the environment where selection takes place differs considerably from the commercial environment of slaughter pigs. The position on the en...

Beach erosion and nest site selection by the leatherback sea turtle Dermochelys coriacea (Testudines: Dermochelyidae) and implications for management practices at Playa Gandoca, Costa Rica.

Leatherback sea turtles (Dermochelys coriacea) nest on dynamic, erosion-prone beaches. Erosive processes and resulting nest loss have long been presumed to be a hindrance to clutch survival. In order to better understand how leatherbacks cope with unstable nesting beaches, I investigated the role of beach erosion in leatherback nest site selection at Playa Gandoca, Costa Rica. I also examined t...

Optimal Randomized Algorithm for the Density Selection Problem

In the paper we consider a generalized version of three wellknown problems: Selection Problem in computer science, Slope Selection Problem in computational geometry and Maximum-Density Segment Problem in bioinformatics. Given a sequence A = (a1, w1), (a2, w2), . . . , (an, wn) of n ordered pairs (ai, wi) of real numbers ai and wi > 0 for each 1 ≤ i ≤ n, two nonnegative real numbers , u with ≤ u...
