Relaxed-plan-based (RPB) heuristics were first proposed by Hoffmann and Nebel for their FF system and are still used by current top-performing planners. Their main characteristic is that they are computed by computing a so-called relaxed plan, which is a plan for a relaxed version of the problem that ignores negative effects of actions. However, still in some domains that humans consider simple...

Where bedforms migiate during deposition, they move upward (climb) with respect to the generalized sediment surface. Sediment deposited on each lee slope and not eroded during the passage of a following trough is left behind as a cross-stratified bed. Because sediment is thus transferred from bedforms to underlying strata, bedforms must decrease in cross-sectional area or in number, or both, un...

Image classification is a very challenging and important problem in the image management and retrieval system. The traditional methods are not effective to the image classification due to the high dimensionality of the image feature space. This paper proposes a method of image classification over a given data set using subset feature set and morphological profile. On the basis of subset feature...

We investigate the use of oblivious, read-once decision graphs as structures for representing concepts over discrete domains, and present a bottom-up, hill-climbing algorithm for inferring these structures from labelled instances. The algorithm is robust with respect to irrelevant attributes, and experimental results show that it performs well on problems considered di cult for symbolic inducti...

Objective The objective of the wheelchair performance evaluation with the PAU was to determine the characteristics which define its level of operation. The intended use for the information collected is to identify the weak performance areas of the power assist. These areas can be addressed in future design iterations. The following characteristics of the power assist device were evaluated in th...

Measurements of rod climbing in A1 give rise to an apparent linear relation between the height rise h and the angular velocity Ω of the rod. We use a White-Metzner model to fit the data and we find that the height rise on the rod deviates from the quadratic dependence on the angular velocity when the viscosity or relaxation time vary with shear rate. When both the relaxation time and the viscos...

The naïve Bayes classifier is built on the assumption of conditional independence between the attributes given the class. The algorithm has been shown to be surprisingly robust to obvious violations of this condition, but it is natural to ask if it is possible to further improve the accuracy by relaxing this assumption. We examine an approach where naïve Bayes is augmented by the addition of co...

Test incorporations are program transformations that improve the performance of generate-and-test procedures by moving information out of the \test" and into the \generator." The test information is said to be \incorporated" into the generator so that items produced by the generator are guaranteed to satisfy the incorporated test. This article proposes and investigates the hypothesis that a gen...

The problem raised in this article is the selection of the most important components from multispectral images for the purpose of skin tumor tissue detection. It occured that 21 channel spectrum makes it possible to separate healthy and tumor regions almost perfectly. The disadvantage of this method is the duration of single picture acquisition because this process requires to keep the device v...

Many researchers have been working on the greedy algorithms for covering array generation; a framework has been built to integrate most of these greedy methods, and more new approaches can be derived from this framework. However, such a framework is affected by multiple dependent or independent factors, which makes its deployment and optimization very challenging. In this paper, we design Hill ...
