RoboCup中型组足球机器人比赛具有高度的对抗性和实时性.比赛中机器人需要针对不同的比赛态势进行角色切换和任务选择.在这种环境下,应用传统人工势场或一般改进型人工势场的路径规划方法都无法得到令人满意的结果.将障碍物与机器人之间的相对速度矢量以及目标与机器人之间的相对速度矢量分别引入人工势场法中,对传统的势场函数进行了改进;并根据机器人的不同角色和任务,采用模糊逻辑方法对势场函数进行修正,提出一种处理多角色多任务环境的改进型人工势场法机器人路径规划方法.仿真试验和实际应用验证了此算法在足球机器人比赛系统中的可行性. 展开更多

Meredith's heroines are radically different from the women generally encountered in Victorian fiction. Characteristically, Meredith constructs a type of female character who, in a social context hostile to any break with convention, refuses to conform to the stereotype of the weak, passive, and dependant woman. In accordance with J. S. Mill's observations in The Subjection of Women (1869), Meredith thought that the progress of society could be possible only through female emancipation and admittance of women into public practice. This paper discusses the themes of marital disintegration and "conscious adultery" that affirm the legitimacy of female pleasure against coercion Thus, the paper will take into consideration the sonnet sequence Modern Love (1862) and one of Meredith's most neglected novels, Lord Ormont and His Aminta (1894), whose heroines are unexpectedly depicted as non-conventional, strong, and proud. A close reading of the texts will reveal the narrative strategies and textual devices through which Meredith exploited a model of womanhood that, by subverting the current ideas on sex, marriage, and gender roles, is able to countermine male "egoism", the only obstacle to the genuine progress of Victorian society toward real democratization 展开更多
