Metasearch information fusion using linear programming

Gholam R. Amin, Ali Emrouznejad, Hamid Sadeghi (2012)

RAIRO - Operations Research

Similarity:

For a specific query merging the returned results from multiple search engines, in the form of a metasearch aggregation, can provide significant improvement in the quality of relevant documents. This paper suggests a minimax linear programming (LP) formulation for fusion of multiple search engines results. The paper proposes a weighting method to include the importance weights of the underlying search engines. This is a two-phase approach...

Method of Linear Programming as an Idea for High School Curriculum

Kelevedjiev, Emil, Iordanka, Gortcheva (2010)

Union of Bulgarian Mathematicians

Similarity:

2010 Mathematics Subject Classification: 97D40, 97M10, 97M40, 97N60, 97N80, 97R80 Since the middle of the 20th century, mathematical modeling by means of optimization problems has been widespread in scientific applications. Together with the software developed, it has a real impact on practice, thus changing the ideas of society about the role of mathematics, computer science, and information technologies. The present paper is aimed to show the accessibility of some basic...

Interactive compromise hypersphere method and its applications

Sebastian Sitarz (2012)

RAIRO - Operations Research - Recherche Opérationnelle

Similarity:

The paper focuses on multi-criteria problems. It presents the interactive compromise hypersphere method with sensitivity analysis as a decision tool in multi-objective programming problems. The method is based on finding a hypersphere (in the criteria space) which is closest to the set of chosen nondominated solutions. The proposed modifications of the compromise hypersphere method are based on using various metrics and analyzing their influence on the original method. Applications of...

A Software Platform for Teaching Programming with Grading Systems Софтуерна платформа за преподаване на програмиране със състезателни системи

Manev, Krassimir, Sredkov, Miloslav, Armyanov, Petar (2011)

Union of Bulgarian Mathematicians

Similarity:

Красимир Манев, Милослав Средков, Петър Армянов - Състезателните системи (СС) са незаменимо средство за организация на състезания по програмиране. Напоследък СС се използват и в обучението по програмиране. В статията е предложена платформа, която да интегрира възможностите на СС, създадени или използвани от авторите. Целта е изграждането на проста и ефективна среда за обучение по програмиране, подпомагаща учебния процес. Специфицирани са основните елементи на платформата, като резултат...

CORE: A Multi-Purpose Programming Contest Repository System CORE - многоцелева система-хранилище за състезания по програмиране

Chaushev, Yani, Sredkov, Miloslav, Manev, Krassimir (2012)

Union of Bulgarian Mathematicians

Similarity:

Яни Чаушев, Милослав Средков, Красимир Манев - Всяко състезание по програмиране използва множество софтуерни инструменти за управление на процесите по време на състезанието. Въпреки че тези инструменти обикновено покриват спецификите на конкретния вид състезание задоволително, те рядко адресират трудностите на дългосрочното съхранение на данни и оперативната съвместимост. В тази статия е представен един софтуерен инструмент адресиращ тези проблеми. Вместо комплексна система, касаеща...

Solving the Crop Allocation Problem using Hard and Soft Constraints

Mahuna Akplogan, Simon de Givry, Jean-Philippe Métivier, Gauthier Quesnel, Alexandre Joannon, Frédérick Garcia (2013)

RAIRO - Operations Research - Recherche Opérationnelle

Similarity:

Application tools for the crop allocation problem (CAP) are required for agricultural advisors to design more efficient farming systems. Despite the extensive treatment of this issue by agronomists in the past, few methods tackle the crop allocation problem considering both the spatial and the temporal aspects of the CAP. In this paper, we precisely propose an original formulation addressing the crop allocation planning problem while taking farmers’ management choices into account. These...
