智慧农业顶层设计与解决方案
近年来，智慧农业发展突飞猛进，众多技术、资金、人才的流入，为农业现代化发展提供了广阔的发展空间与平台机遇。在刚举办的“互联网+现代农业”暨智慧农业高峰论坛上，就当前智慧农业、互联网+现代农业的发展现状，主办方托普云农副总经理朱旭华接受了采访，立足智慧农业的发展生态圈，呼吁多方力量携手共同推进互联网+现代农业的发展。“智慧农业作为一个非常巨大的市场，不可能是一家企业能做的完的、做的好的，要想持续健康发展，还需要更多的合作共赢、互帮互助。”在朱旭华看来，这种合作并不是简单的你依附我，我依附你，而是产生倍增效应，1+1一定要大于2。一号文件代表政府的引导和市场的方向，尤其是农业供给侧改革这个概念。

基于粒子群遗传算法的云计算任务调度研究
对云计算任务调度进行了研究，针对用户满意度和云提供商利益需求，提出一种融合粒子群和遗传算法的PSOGA改进算法。首先根据云环境特点对虚拟机资源进行分类，同时引入任务‐资源满意度距离、资源综合性能概念；然后对粒子群初始粒子操作进行优化，来提高粒子质量；最后为克服粒子易陷入局部最优解问题，加入遗传算法（GA）的交叉、变异操作，扩展粒子的搜索空间。仿真结果表明，该调度策略提高了用户满意度的同时减少了任务的完成时间，是云平台下一种有效的任务调度策略。Computer engineering and applications[0,1]Ka By+M=85,7,4,7,41 aya+B+rBr0.10.20.7(9,1,25,7)(9,25,5,7)=(1,0,0,1,1)3 a oB∑01(1,0,1,1)④0.9(1,1,0,1)=(1xx,1)010.109(3,2,1,5,4)∞(1,0,1,1,1)=(3x,15,4)GA3.2Computer engineering and applications0.36Cloudsim 3.0CloudsimDatacenter Brokerbind cloudlettovm=0.82bind CloudlettovmMyclipse100PSOGAPSOGAK=844%Cloud[1000040000rand([150,200rand()]预处理任务及資、「5001000rand(]源,并更新虚拟机计算任务-资谅满总度距离[60100rand()ndo初始负载从可用资源随机生|根据得致的任务最PSOGA成S3/4个子佳虚拟机类型生成S/4个粒子PSOPSOGAGA初始化S个粒了的还200度,并设置最大迭代次数L和 fitness=tPSOGA很据車新定义的粒了探作,计算 fitness值,并更新pb利gb根据规则选择粒了进亻[15交叉变异探作,并计算fitness值,更新忡群(12)达到最大次效LL=L+1fitness阈值结太,得到最优解(13)M=200300200200LPSOs Lo n PsoGAPSOGAPSOGAGAComputer engineering and applications80070600s■PSO400AGA300■ PSOGA200PSOGAPSO GA100PSO GA0第一批第二批第三批PSOGAPSO GAPAOGAPSOGA2.5PSOPSOGAA0.5PSOGA第一北第二批第批PSOGAPSO GA5400190r170015001301100西GAn□1sGAGA了0050o笫一批第二批第二批43.532.5NGA□05第一枇第二批第三批Computer engineering and applications基于粒子群遗传算法的云计算任务调度研究万F据WANFANG DATA文献链接作者王菠,张晓磊作者单位:重庆人学计算机学院,重庆400044刊名:计算机工程与应用英文刊名:Com uter Engineering ar d Appl ications年,卷(期)2013Axfe:http://d.wanfangdata.concn/periodiCalpre8fb5c222-8042-4959-ba95-2a3a31f59b2e.aspx
