Solution of multidimensional knapsack problems via cooperation of dynamic programming and branch and bound

Boyer, Vincent; Baz, Didier El; Elkihel, Moussa - In: European Journal of Industrial Engineering 4 (2010) 4, pp. 434-449

This article presents an exact cooperative method for the solution of the multidimensional knapsack problem (MKP) which combines dynamic programming and branch and bound. Our method makes cooperate a dynamic programming heuristics based on surrogate relaxation and a branch and bound procedure....

Modèle i-o régional : méthode de génération aléatoire des coefficients soumise à contrainte d'exactitude semi-partitive

André-Fas, Catherine - In: Revue d'économie régionale et urbaine avril (2001) 2, pp. 197-227

This paper introduces a new method of regional Input-Output table?s construction. Stemmed from both contributions and critics of Input-Output research, it constitutes a compromise between surveys techniques where regional coefficients are directly collected and nonsurveys techniques where...
