    Description: 利用Gleeble-3800模拟X70大变形管线钢奥氏体再结晶区和非再结晶区的双道次变形、弛豫及加速冷却过程。采用金相显微镜、SEM等试验方法,研究了空冷驰豫时间及冷却速度对显微组织的影响。结果表明:从770℃弛豫到700℃后开始快冷的冷速为8.1℃/s时,驰豫时间(53.8~100s)对组织、硬度的影响较小;不同弛豫时间对应的组织均为双相组织,马氏体/贝氏体呈岛状分布在铁素体基体上,铁素体晶粒大小不一,碳化物多且密集;从770℃弛豫到700℃后采用水冷时,随着驰豫时间延长,双相组织中铁素体增多,硬度降低;相同驰豫时间及水淬方式冷却试样的硬度及马氏体/贝氏体数量明显高于8.1℃/s冷却的试样。
    Description: The process of rolling in the recrystallized region and the nonrecrystallized region of austenite, relaxation and cooling in X70 pipeline steels with high deformation resistance were simulated using Gleeble-3800. The influence of relaxation time and cooling rate on the microstructure and hardness was investigated by OM and SEM. The results indicate that the influence of relaxation time on the microstructure and hardness was not obvious when cooling at 8.1 ℃/s after relaxation from 770 ℃ to 700 ℃. Dual-phase microstructure with martensite/banite inlands in ferrite matrix can be obtained for relaxation time between 53.8 s and 100 s, which has different size ferrite grain with dense carbides. The amount of ferrite increases and hardness decreases with relaxation time increasing, when water-quenched after relaxation from 770℃ to 700℃. Under the same relaxation time, the hardness and amount of martensite/banite with water quenching are higher than those with cooling rate of 8.1 ℃/s.

    Description: 联盟结构是对kent集合的一个划分,通过联盟形成联盟结构,可以使Agent之间形成有效合作,完成单个kent所不能完成的任务。本文提出了BDP来求最优联盟结构,该算法利用整数二部拆分来生成二部划分,并利用二部拆分的界来对搜索空间进行限界。随后把该算法与DP算法做了理论和实验分析,理论上得出BIDP所需要的空间比DP减少33.3%。实验表明,当联盟值满足均匀分布和正态分布,BIDP在21个Agent的情况下,搜索空间比DP减少35%和92%。最后对求最优联盟结构的确定式算法作了总结,即时间复杂度的上界是O(3n),下界是Ω(2n),空间复杂度是θ(2n)。
    Description: Coalition structure is a partition of the agent set, forming a coalition structure by coalition can make agents cooperate effectively and fulfill the tasks that a single agent can not. In this paper, we propose a BIDP (Bipartite of Integer Dynamic Programming) algorithm to solve the optimal coalition structure generation, which adopts the bipartite of integer to generate bipartite partitions, and takes the bound of integer bipartite as the bound of the search space. And a theoretical analysis proves that BIDP can save 33.3% memory in any case than DP (Dynamic Programming). An experiment analysis shows that BIDP can save 35% and 920//00 searching numbers on 21 agents when the coalition values meet the uniform distri- bution and normal distribution. Finally, the paper gives a verdict that the time complexity of the determinant algorithm to solve OCS is between Ω(2n ) and O(3n ), and the space complexity is θ(2n ).

    Description: 提出一种用于生成最优联盟结构的任意时间算法LVAA。利用分支限界技术和剪枝函数搜索联盟结构图的,L1、L2和最顶层后,根据整数拆分对剩余的搜索空间进行横向剪枝,并在横向剪枝剩余的子空间内进行纵向剪枝,从而求得最优联盟结构。实验结果表明,该算法的剪枝效率较高,并能在任意时间点上找到最优值。
    Description: This paper proposes Lateral and Vertical Anytime Algorithm(LVAA) to generate optimal coalition structure. It uses a branch and bound technique and pruning function to search L1, L2 and top layers of the coalition structure graph. According to the conception of the integer partition, it prunes the space horizontally, and then prunes in the remaining subspace vertically and finds the optimal coalition structure value. Experimental results show that pruning efficiency of the algorithm is high, and it can find the current optimal value at anytime.
