为了克服乌鸦搜索算法搜索能力弱、易陷入局部最优之不足,提出新的以优秀个体记忆位置为导向的改进乌鸦搜索算法(EICSA):基于个体贮藏食物量之多少,种群中多数个体划归为普通个体、少数贮藏食物量较多的个体划归为优秀个体.优秀个体只在其贮藏食物的巢穴附近开展局部搜索活动.多数普通个体以优秀个体贮藏食物之巢穴为导向,在算法前期以较大步长进行全局探索,保持了种群的多样性;算法后期则以较短步长进行局部开发,使算法的全局探索能力和局部开发能力均得到了增强.通过12个基准函数和3个工程应用问题的数值实验,结果表明EICSA的全局优化能力得到了明显提高,在函数和工程应用问题优化中具有较快的全局收敛速度、较好的优化精度和稳定性.

中国儿童超重肥胖比率不断增长,危害儿童身心健康.因此,有必要关注儿童肥胖问题,探究儿童饮食行为与肥胖的脑结构关联.慢食行为是儿童饮食行为中潜在的重要关键因素,在增强饱腹感的同时减少能量摄入,能够有效预防和改善肥胖问题,但已有研究未深入探讨其脑结构基础.本研究选取99名儿童,年龄范围为9~12岁,平均年龄为10.476±0.855岁,通过儿童饮食行为量表的慢食维度测量儿童的慢食行为,使用磁共振成像仪采集脑影像数据,获取脑区皮层体积并映射到中国儿童脑体积常模上,进一步得到儿童脑区皮层体积在常模上的相对位置参数.相关分析结果表明,身体质量指数(body mass index,BMI)与慢食行为(r=-0.383,P<0.001)呈负相关,与舌回皮层体积(r=0.304,P=0.002)和后扣带回皮层体积呈正相关(r=0.392,P<0.001),慢食行为与后扣带回皮层体积呈负相关(r=‒0.221,P=0.028).中介模型表明后扣带回皮层体积在儿童慢食行为与身体质量指数之间存在中介作用,中介效应值为‒0.088.后扣带回具有重要的奖赏和执行控制功能,引导注意力焦点(进食体验、进食过程)和支持内部导向认知(奖赏状态、饱腹状态).慢食行为的儿童感知进食过程并识别饱腹信号,适时停止进食行为,而快速进食的儿童在进食体验带来的奖赏中忽视了饱腹状态,往往与过度进食产生肥胖有关.本研究提供了儿童慢食行为和身体质量指数稳健的脑结构基础证据,并且为从减缓餐内饮食速度入手改善儿童肥胖问题提供理论参考.
