Hierarchical Wave Functions Revisited
The trial wave function of the fractional quantum Hall effect (FQHE) on a disk at filling ν = 1/m with m an old integer is given by the famous Laughlin wave function [1]. Laughlin wave function had been constructed on a spheric or a toric surface later in refs. [2, 3]. When ν 6= 1/m, there are several proposals for constructing the trial wave function, notably Halperin’s hierarchical wave funct...
متن کاملHierarchical Heuristic Search Revisited
Pattern databases enable difficult search problems to be solved very quickly, but are large and time-consuming to build. They are therefore best suited to situations where many problem instances are to be solved, and less than ideal when only a few instances are to be solved. This paper examines a technique hierarchical heuristic search especially designed for the latter situation. The key idea...
متن کاملHierarchical termination revisited
During the past two decades, term rewriting has gained enormous importance in various fields of computer science. Among other things, term rewriting constitutes a Turing-complete computational model which is closely related to functional programming. In other words, term rewriting systems (TRSs) can be viewed as programs. It is a well-known programming paradigm in computer science that programs...
متن کاملSOLVING FUZZY LINEAR PROGRAMMING PROBLEMS WITH LINEAR MEMBERSHIP FUNCTIONS-REVISITED
Recently, Gasimov and Yenilmez proposed an approach for solving two kinds of fuzzy linear programming (FLP) problems. Through the approach, each FLP problem is first defuzzified into an equivalent crisp problem which is non-linear and even non-convex. Then, the crisp problem is solved by the use of the modified subgradient method. In this paper we will have another look at the earlier defuzzifi...
متن کاملCHC++: Coherent Hierarchical Culling Revisited
We present a new algorithm for efficient occlusion culling using hardware occlusion queries. The algorithm significantly improves on previous techniques by making better use of temporal and spatial coherence of visibility. This is achieved by using adaptive visibility prediction and query batching. As a result of the new optimizations the number of issued occlusion queries and the number of ren...
