Interface Splitting Algorithm for diagonal dominant tridiagonal matrices
The interface-splitting algorithm solving diagonal dominant tridiagonal systems in parallel is presented. The algorithm requires only the nearest neighbor communication with minimum number of communications and data transfer. Unlike the existing divide and conquer algorithms solving this problem, the proposed algorithm only requires one phase of synchronisation and bidirectional links can be fu...

24 restriction. As and , the minimum of δ (l) is achieved on the boundary of R. It is not difficult to see that this minimum is in x = y = , independently of the values of the greek letters. With this, we can see that: Now, if , we have: which allows to finish the proof: x y , () R ∈ 0 δ l 1 − () 1 − , [ ] 0 δ l 1 − () 1 − , [ ] × = x ∂ ∂δ l () 0 ≠ y ∂ ∂δ l () 0 ≠ δ l 1 − () 1 − δ l () δ l 1 − ...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
15 صفحه اولA Critical Survey of Performance Indices for Multi-Objective Optimisation
A large number of methods for solving multiobjective optimisation (MOO) problems have been developed. To compare these methods rigorously, or to measure the performance of a particular MOO algorithm quantitatively, a variety of performance indices (PIs) have been proposed. This paper provides an overview of the various PIs and attempts to categorise them into a certain number of classes accordi...
