Chasing Constrained
We investigate the implication problem for constrained tuple-generating dependencies (CTGDs), the extension of tuple-and equality-generating dependencies that permits expression of semantic relations (constraints) on variables. The implication problem is central to identifying redundant integrity constraints, checking integrity constraints on constraint databases, detecting the independence of ...
متن کاملChasing chaos
Both simple and hybrid genetic algorithms encounter difficulties when presented with a function which has multiple values. Similarly, changing environments or functions which change rapidly present other problems. This paper presents an algorithm that is capable of coping with both of these scenarios: it can accommodate multiple solutions simultaneously and can track changes in optima efficient...
متن کاملChasing CHOOZ
Since 1998 when SuperKamiokande announced incontrovertible evidence of neutrino oscillations, a series of experiments have unravelled most of the fundamental neutrino parameters. Two important pieces of information still await determination: the absolute value of the masses, together with their hierarchy, and the third mixing angle, for which there only exists a limit set by the CHOOZ experimen...
متن کاملChasing Science Culture
Representing networks is a major interest of researchers in information visualization. In this article, I present novel visualization techniques based on Jacques Bertin’s reorderable matrices. As the human brain is particularly effective at processing visual information, researchers in computer science developed a number of visual exploration systems to analyze graphs and networks. In the last ...
متن کاملChasing Polarized Order Dependencies
Dependencies have played a significant role in database design for many years. They have also been shown to be useful in query optimization. In this paper, we discuss the new type of dependency for polarized lexicographically ordered sets of tuples. We introduce formally the concept of polarized order dependencies (PODs). We discuss their potential significance for database systems, and present...
