基因表达式编程中动态适应的远缘繁殖策略

传统基因表达式编程采用静态适应度函数,影响了后期进化速度和整体质量。提出了远缘繁殖策略和动态适应度函数策略,远亲繁殖并及时变换评估个体的标准,增加多样性并有利于选择优质个体;实验表明,将远缘繁殖和动态适应度函数策略结合,有效地改善了传统GEP的性能,进化代数平均下降达10%,平均最高适应度值提高7%~14%,最高适应度提高达7%以上,进化的成功率提高达30%以上。

Eliminability of cut in hypersequent calculi for some modal logics of linear frames

Hypersequent calculi, introduced independently by Pottinger and Avron, provide a powerful generalization of ordinary sequent calculi. In the paper we present a proof of eliminability of cut in hypersequent calculi for three modal logics of linear frames: K4.3, KD4.3 and S4.3. Our cut-free calculus is based on Avron's HC formalization for Gödel–Dummett's logic. The presented proof of eliminability of cut is purely syntactical and based on Ciabattoni, Metcalfe, Montagna's proof of eliminability of cut for hypersequent calculi for some fuzzy logics with modalities.     

Optimal water allocation through a multi-objective compromise between environmental,social, and economic preferences

Raising water demands and insufficient freshwater resources are the main reasons of water conflicts in transboundary watersheds. Sustainable water allocation can be a resolution for water disputes as it addresses simultaneously economic, social and environmental benefits. In this paper, a multi-objective model is introduced, which leads to sustainable water allocation of transboundary watersheds taking into account all these three aspects. Five water allocation objectives are proposed for this model in which three of them address the social factors and others represent the economic and environmental preferences. The Compromise Programming technique is employed to solve the applied model to the Sefidrud Basin, Iran and several water allocation schemes are provided based on various weights combinations. The results of the model elucidate that the proposed model can allocate 83 percent of the Basin's water resources, to its stakeholders in a sustainable way while the environmental demand is satisfied.
