To overcome the shortcomings of existing local search ability and to easily obtain the local opti- mal solution of artificial bee colony algorithm ( ABC) ，a new modified artificial bee colony algorithm ( MABC) is proposed using the development trend of known solution space predicted by Markov Chain.

57779 最后以 10 个典型函数为测试用例，从结果精度、收敛速度、分割参数和运行时间 4 个方面进行验证，实验结果表明，MABC 算法在求解精度和收敛速度上高于 ABC 算法，但运行时间略长，验证了理论分析的结果. The performances of the ABC and MABC are analyzed from two aspects: convergence performance and algorithm complexity. Using 10 typical functions as test cases，Experiments are carried out in four aspects: result precision，convergence speed，segmentation parameters and running time.

57782 针对基于位置服务中移动终端用户位置隐私泄露问题，提出了一个基于相似轨迹替代查询的位置隐私保护方案. Aiming at the problem of privacy leakage of mobile terminal users in location based service，a location privacy protection scheme is proposed based on similar trajectory replacement query.
57783 该方案在基于位置服务请求的用户及候选者身份匿名化的基础上，采用相似轨迹函数挑选出一定时间间隔内和用户轨迹相似度最高的候选者; In this scheme，identities of the requesting user and all the candidates are annonymized. By adopting the similar trajectory function to calculate the trajectory similarities between all the candidates and the requesting us- er at certain time intervals，the optimal candidate with highest similarity is selected to represent reques- ting user in requesting LBS.
