C Gamble,S Hollis - 《Journal of Clinical Epidemiology》 被引量: 135发表: 2005年 The worst-case analysis of the MULTIFIT algorithm for scheduling nonsimultaneous parallel machine In this paper we consider the nonsimultaneous multiprocessor scheduling problem, or NMSP for short. The NMSP is a ...
3.1Preliminaries for the Algorithm We make use of the following definitions, see Fig.3. Forr_{out } \ge r_{in } > 0and a container disk\mathcal {C}such thatr_{out } \le 2 r_{in }, we define aringR:=R[r_{out }, r_{in }]of\mathcal {C}as the closure ofr_{out }\se...
We also study the worst-case behavior of the well-known first-fit algorithm, and show that it requires at most 2.52Llog 2 N+5L wavelengths (small variants of these constants are proven as well). When limited wavelength conversion is allowed, we first show how to use expanders to insure ...
By reducing the search area the algorithm complexity and the computation time can be reduced. Rossi and Lanzetta [4] proposed a GA to evaluate roundness, considering a search space for the minimum zone center with the centroid of the roundness profile as the center and a radius of about 0.43...
Supplier selection is regarded as the primary goal of supply chain management (SCM) because it affects its performance, productivity, pleasure, flexibility, and system speed in lockdown. A new method is proposed based on a multi-stage fuzzy sustainable supplier index (FSSI). Experts can use the...
I hope I’m wrong but the banksters don’t want to be blamed for the pending bust which is going to be epic and currently being held up by algorithm. They need war and Hillary will deliver. It amazes me that most Americans just can’t connect the dots. They are not curious one bit...
2. Algorithm LPT In this section, LPT is customized to be fit to handle our problem. Although, essentially the same algorithm can be found in [9], it is presented here again for completeness. We introduce a few notations to facilitate our presentation of the algorithm. For an arbitrary set...
对于问题P2||Cmin,证明对偶阈值算法DA2(1/7)的最坏情况界为6/7,并证明此界为紧界;对于问题P3||Cmin,进而提出层次对偶阈值算法TDA3(ε),并证明当ε取2/11时,算法的最坏情况界为9/11。 2. In on- line version,theworst-case ratioof LS being 1/m is proved,so LS is the optimal algorithm for...
