Knapsack problems range over a large sphere of real world challenges [?]. For example, every year a professor has to decide her new “squad” of students/staff from possibly hundreds of candidates, while having a restricted budget of funding in consideration. Moreover, in many cases, she has to resort to her colleagues and senior students to make comparisons among the candidates. The difficulties of...
The delay tolerant mobile sensor network distinguishes itself from conventional sensor networks by several unique characteristics such as node mobility, loose connectivity, and delay tolerability. Therefore, traditional data gathering methods cannot be applied. In this paper, a novel data gathering method named average contact probability-based data delivery scheme (ACPBD) is proposed. ACPBD introduces...
As one of the popular evolutionary algorithms, differential evolution (DE) shows outstanding convergence rate on continuous optimization problems. But prematurity probably still occurs in classical DE when using relatively small population, which is discussed in this paper. Considering that large population may significantly raise the computational effort, we propose a modified DE using smaller population...
