چکیده

Though the divide-and-conquer algorithm is a powerful technology, but it is difficult to be used in practice, so the design of this algorithm should be regulated in the teaching. In this article, the teaching process and the characters of the divide-and-conquer algorithm are studied when solving the problem of chessboard coverage. Aiming at the deficiency that the existing teaching method uses skills in decomposing sub-problems and increases the teaching difficulty, the coverage sequence of L-type dominoes is improved. The improved algorithm can keep consistent with the divide-and conquer strategy and standardize the iterative process, and increase the normative character and the consistence of the algorithm, and hence achieve ideal teaching result.

Knowledge Reduction Based on Divide and Conquer Method in Rough Set Theory

The divide and conquer method is a typical granular computing method using multiple levels of abstraction and granulations. So far, although some achievements based on divided and conquer method in the rough set theory have been acquired, the systematic methods for knowledge reduction based on divide and conquer method are still absent. In this paper, the knowledge reduction approaches based on...

Free Vibration Analysis of Repetitive Structures using Decomposition, and Divide-Conquer Methods

This paper consists of three sections. In the first section an efficient method is used for decomposition of the canonical matrices associated with repetitive structures. to this end, cylindrical coordinate system, as well as a special numbering scheme were employed. In the second section, divide and conquer method have been used for eigensolution of these structures, where the matrices are in ...

Towards More Effective Tableaux Reasoning for CKR

Representation of context dependent knowledge in the Semantic Web is a recently emergent issue. A number of logical formalisms with this aim have been proposed [3, 11, 14]. Among them is the DL based Contextualized Knowledge Repository (CKR) [13]. One of the mostly advocated advantages of context based knowledge representation is that reasoning procedures can be constructed by composing local r...

On Parity based Divide and Conquer Recursive Functions

The parity based divide and conquer recursion trees are introduced where the sizes of the tree do not grow monotonically as n grows. These non-monotonic recursive functions called fogk(n) and f̃ogk(n) are strictly less than linear, o(n) but greater than logarithm, Ω(logn). Properties of fogk(n) such as non-monotonicity, upper and lower bounds, etc. are examined and proven. These functions are us...
