The recent progress in solving the unbounded knapsack problem (UKP) is tightly related to the phenomenon of dominance which contributes to eliminate the non-prootable object types and reduce drastically the solutions search space. We focus here on the analysis of the computational results obtained by us by (EDUK) for EEcient Dynamic programming for UKP. This new dynamic programming algorithm is...

the problem of good and bad in philosophy and theology can be discussed from two perspectives, ontological and epistemological. the problem that we're seeking to answer in this paper is that: does the theory of “al-idrakat al-i'tibariyah” (constructive perceptions) has presented a new solution for it?  if yes, which way it has used to deal with the problem (ontological or epistemologi...

in this paper a new problem of three stage disassembly-assembly scheduling is introduced and reviewed. this problem, which was arisen from the aviation industry characteristics, is a generalization of the two stage assembly scheduling problem. products (helicopters) in the aviation industry return to assembler for annual overhaul repair services. in the first stage helicopters are disassembled ...

In this paper, we propose the new concept of optimal solution for fuzzy variational problems based on the possibility and necessity measures. Inspired by the well–known embedding theorem, we can transform the fuzzy variational problem into a bi–objective variational problem. Then the optimal solutions of fuzzy variational problem can be obtained by solving its corresponding biobjective variatio...
