针对目前传统智能优化算法在解决复杂非线性多参数优化问题时所存在的收敛速度慢、容易陷入局部最优、时间复杂度高及易于早熟等问题,受人体神经-内分泌-免疫(neuro endocrine immune,NEI)系统的启发,提出了一种基于生物调节机制的人工蜂群智能算法(NEI-ABC)。在传统人工蜂群算法(artificial bee colony,ABC)结构基础上,该算法增设了蓝光引导单元、蜜源调控单元和触角定向单元,极大提高了引领蜂、侦查蜂和跟随蜂的搜寻和探索能力,从而使得其全局寻优性能得到提升。仿真实验表明NEI-ABC算法相对其他传统算法具有较高寻优性能,且在油田注采产量规划等复杂优化问题解决中发挥积极作用。

The modulation of topological electronic state by an external magnetic field is highly desired for condensed-matter *** to achieve this have been proposed theoretically,but few can be realized ***,combining transverse transport,theoretical calculations,and scanning tunneling microscopy/spectroscopy(STM/S)investigations,we provide an observation that the topological electronic state,accompanied by an emergent magneto-transport phenomenon,was modulated by applying magnetic field through induced non-collinear magnetism in the magnetic Weyl semimetal EuB6.A giant unconventional anomalous Hall effect(UAHE)is found during the magnetization re-orientation from easy axes to hard ones in magnetic field,with a UAHE peak around the low field of 5 kOe.
