چکیده

Le problème de l’ensemble minimal de paquets (minimal hitting set of bundles problem ou HSB) est défini comme suit. On dispose d’un ensemble E = {e1, e2, . . . , en} de n éléments. Chaque élément ei (i = 1, . . . , n) a un coût positif ou nul ci. Un paquet b est un sous ensemble de E . On dispose aussi d’une collection S = {S1, S2, . . . , Sm} de m ensembles de paquets. De manière plus précise, chaque ensemble Sj (j = 1, . . . ,m) est composé de g(j) paquets distincts notés bj , b 2 j , . . . , b g(j) j . Une solution du problème HSB est un sous ensemble E ′ ⊆ E tel que pour tout Sj ∈ S , au moins un paquet est couvert, i.e. bj ⊆ E ′. Le coût total de la solution, noté C(E ′), est

Parameterizations of hitting set of bundles and inverse scope

Hitting Set of Bundles generalizes the ordinary Hitting Set problem in the way that prescribed bundles of elements rather than single elements have to be put in a hitting set. The goal is to minimize the total number of distinct elements in the solution. First we prove that Hitting Set of Bundles, with the number of hyperedges and the solution size as parameter, is W [1]-complete. This contrast...

On the Minimum Hitting Set of Bundles Problem

We consider a natural generalization of the classical minimum hitting set problem, the minimum hitting set of bundles problem (mhsb) which is defined as follows. We are given a set E = {e1, e2, . . . , en} of n elements. Each element ei (i = 1, . . . , n) has a non negative cost ci. A bundle b is a subset of E . We are also given a collection S = {S1, S2, . . . , Sm} of m sets of bundles. More ...

Processing of Lexical Bundles by Persian Speaking Learners of English

Formulaic sequence (FS) is a general term often used to refer to various types of recurrent clusters. One particular type of FSs common in different registers is lexical bundles (LBs). This study investigated whether LBs are stored and processed as a whole in the mind of language users and whether their functional discourse type has any effect on their processing. To serve these objectives, thr...

Comparing Lexical Bundles in Hard Science Lectures; A Case of Native and Non-Native University Lecturers

Researchers stated that learning and applying certain set of lexical bundles of native lecturers by non-native lecturers would help students improve their proficiency through incidental vocabulary input. The present study shed light on the lexical bundles in hard science lectures used by Native and Non-native lecturers in international universities with the main purpose of analyzing the structu...

Hitting and Piercing Rectangles Induced by a Point Set

We consider various hitting and piercing problems for the family of axis-parallel rectangles induced by a point set. Selection Lemmas on induced objects are classical results in discrete geometry that have been well studied and have applications in many geometric problems like weak epsilon nets and slimming Delaunay triangulations. Selection Lemma type results typically bound the maximum number...
