The electromagnetism-like (EM) algorithm is a meta-heuristic optimization algorithm,which uses a novel searching mechanism called attraction-repulsion between charged particles.It is worth pointing out that there are two potential problems in the calculation of particle charge by the original EM algorithm.One of the problems is that the information utilization rate of the population is not high,and the other problem is the decline of population diversity when the population size is much greater than the dimension of the problem.In contrast,it is more fully to exploit the useful search information based on the proposed new quadratic formula for charge calculation in this paper.Furthermore,the population size was introduced as a new multiplier term to improve the population diversity.In the end,numerical experiments were used to verify the performance of the proposed method,including a comparison with the original EM algorithm and other well-known methods such as artificial bee colony (ABC),and particle swarm optimization (PSO).The results showed the effectiveness of the proposed algorithm.

丈夫的单位今天下午聚餐。独自吃过晚饭，我洗了个澡，在阳台上边玩手机边晾头发。就在我准备起身离开阳台的时候，一个女人进入了我的视线。 此时太阳距离西山顶很近，就像一个迟暮的人，散发着缺乏温度的光。 那个女人就在这昏黄的天光中迟疑地朝着这个小区走来。不是本地人，我一看就知道，她没有在一个小县城常年居住，对一切了然于胸的那种笃定和从容，也没有乡下人那种惶惑甚至紧张。她并不急于赶路，而是边走边四下观望
躺在布满灰尘的日子里 十九楼的高度让人窒息 白色窗帘后面 世界小如一道缝隙 居高临下让我恐慌 失重的错觉 高楼会轰然倒塌 自己会粉身碎骨 楼下彻夜轰鸣 施工的人没有睡 便坦然接受了失眠 在这狭长拥塞的城市 还有什么比宽容更值得拥有 夜 光 从我所在的五楼窗户往外看 城市微缩如一扇窗 高楼里传出微弱的灯光 马路上的车辆，变得越来越少 繁华渐入衰老之势，三个人走进药
