Approximation of set multi-cover via hypergraph matching

Autor: Anand Srivastav, Abbass Gorgi, Mohamed Hachimi, Mourad El Ouali

Publikováno v: Theoretical Computer Science. 845:136-143

For a given b ∈ N n and a hypergraph H = ( V , E ) with maximum degree Δ, the b-set multicover problem which we are concerned with in this paper may be stated as follows: find a minimum cardinality subset C ⊆ E such that no vertex v i ∈ V is c

An Intermediate Representation-based Approach for Query Translation using a Syntax-Directed Method

Autor: Hassana Nassiri, Mohamed Hachimi, Mustapha Machkour

Publikováno v: International Journal of Advanced Computer Science and Applications. 11

We aspire to make one query reasonably sufficient to extract data regardless of the data model used in our research. In such a way, users can freely use any query language they master to interrogate the heterogeneous database, not necessarily the que

Approximation algorithm for the Multicovering Problem

Autor: Anand Srivastav, Mohamed Hachimi, Mourad El Ouali, Abbass Gorgi

Let $$\mathcal {H}=(V,\mathcal {E})$$ be a hypergraph with maximum edge size $$\ell $$ and maximum degree $$\varDelta $$ . For a given positive integers $$b_v$$ , $$v\in V$$ , a set multicover in $$\mathcal {H}$$ is a set of edges $$C \subseteq \math

One query to retrieve XML and Relational Data

Autor: Mustapha Machkour, Mohamed Hachimi, Hassana Nassiri

Publikováno v: FNC/MobiSPC

This paper presents a way to query databases of different models, namely XML and the relational model. As they possess some robust features in data exchange and extraction. Also, the tremendous amount of research to query data presented in these two
