A global convergent algorithm is proposed to solve bilevel linear fractional-linear programming, which is a special class of bilevel programming. In our algorithm, replacing the lower level problem by its dual gap equaling to zero, the bilevel linear fractional-linear programming is transformed into a traditional sin- gle level programming problem, which can be transformed into a series of linear fractional programming problem. Thus, the modi- fied convex simplex method is used to solve the infinite linear fractional programming to obtain the global convergent solution of the original bilevel linear fractional-linear programming. Finally, an example demonstrates the feasibility of the proposed algorithm.

Partial cooperation models are studied for many years to solve the bilevel programming problems where the follower’s optimal reaction is not unique. However, in these existed models, the follower’s cooperation level does not depend on the leader’s decision. A new model is proposed to solve this deficiency. It is proved the feasibility of the new model when the reaction set of the lower level is lower semicontinuous. And the numerical results show that the new model has optimal solutions when the reaction set of the lower level is discrete, lower semi-continuous and non-lower semi-continuous.

By applying Kuhn-Tucker condition the quadratic bilevel programming, a class of bilevel programming, is transformed into a single level programming problem, which can be simplified by some rule. So we can search the optimal solution in the feasible region, hence reduce greatly the searching space. Numerical experiments on several literature problems show that the new algorithm is both feasible and effective in practice.

Considering the dynamic character of repeated games and Markov process, this paper presented a novel dynamic decision model for symmetric repeated games. In this model, players＇ actions were mapped to a Markov decision process with payoffs, and the Boltzmann distribution was intousluced. Our dynamic model is different from others＇ , we used this dynamic model to study the iterated prisoner＇ s dilemma, and the results show that this decision model can successfully be used in symmetric repeated games and has an ability of adaptive learning.

Salt and saline-alkaline stress seriously threaten crop production and food security worldwide(Yang and Guo,2018).Identifying genes that confer tolerance to these conditions without yield penalty would help mitigate this problem through molecular breeding(Liang et al.,2023;Sahu and Liu,2023).Although numerous stress-tolerance genes have been identified,their application potential in molecular breeding has rarely been confirmed through multi-year and multi-site field trials.

本文应用反向传播(back-propagation,BP)神经网络方法研究随机Origin-Destination(OD)需求的城市道路交通网络设计问题.假设OD交通需求量服从某一分布,首先通过蒙特卡罗模拟的方法得到训练样本对神经网络进行训练并用测试样本测试所得到的神经网络,然后运用训练好的神经网络预测了系统总出行时间.将Nine-node网络作为测试网络,比较分析了不同样本规模下BP神经网络与蒙特卡罗模拟方法得出的结果和OD交通需求服从不同分布时系统总出行时间的分布情况.结果表明,BP神经网络的方法能够较好预测系统总出行时间的分布,且与蒙特卡罗模拟计算相比,能够产生一个合理且较窄的预测区间;当OD交通需求服从均匀分布、正态分布和对数正态分布时,系统总出行时间分布较为相似,接近正态分布.
