FR conjugate gradient methods with perturbations are proposed. The global convergence property of the first method is proved under the condition of main directions' sufficient descent. Whereas, in the proof of the convergence for the other two methods, we only need main directions' descent. Importantly and quite interesting, boundedness conditions such as objective function being bounded below, boundedness of level set are not needed. Chapter 5 presents a version of Dai-Yuan conjugate gradient method with perturbations.

Fri particular, the Wittmann-type strong law of larg numbers for independent random variables is generalized to the case of NA random variables. We also present the sufficient and necessary condition of the laws of logarithm, and we extend Teicher-type strong law of the large numbers for sequence of NA random variables. Some of the laws of iterated logarithm of Teicher-type, Egorov-type arid Wittmann-type for sequence of NA random variables are obtained.

通过实证分析可以得出以下结论:(1)强化模型和BBAM在一定程度、一定条件内都能较好的刻画用户网络文献检索行为;(2)学习的发生是与特定的外部场景相联系的,在通常的非强外在约束下,有限理性个体进行随机决策时,其行为同时包含了有意识的理性计算和无意识的规则遵循;(3)在随机决策过程中,个体可能发生的认知进化应是有意识指导的结果,但收敛的方向却受到至少三个因素的影响:初始的信念状态、对反馈信号的主观判断能力、试错的次数。
