/**

|
* Group presents a rectangle organ zone, Group only arranges a group of cells
|
||||||
|
*
|
||||||
|
* 在2.0之前,CellGroup是线型,不具备可进化性。在2.0之后引入Group概念,Group是矩形,大小可以覆盖整个大脑,也可以小到单个细胞。可以进行位置、大小变动、复制、分裂等多种形式的变异
|
||||||
|
*
|
||||||
|
* 为了与旧版CellGroup区分,新版的这个类命名为Group,它代表了一组分布于一个正方形内的细胞群,细胞数量、每个细胞的触突连接方式等参数由当前Group决定,
|
||||||
|
* 可以说每一种Group代表了一种神经网络算法, 通过无数个Group随机的分布、进化、变异,达到最终脑结构适应环境的变化
|
||||||
|
* Group会参与遗传和进化,但是它生成的细胞不会参与遗传。 各个Group生成的细胞相加总和就是脑细胞总数。
|
||||||
|
*
|
||||||
|
* Group在脑活动中不起作用,可以把Group比作播种机,把种子排列好后,就撒手不管了,在遗传过程中有一个fat参数,如果细胞活跃多,则Group保留及变异的可能性大,反之则舍弃掉。
|
||||||
|
* Group是器官的一种,所以蛋里存放着所有Group的位置、大小、内部参数等信息,但是蛋里面不保存具体的细胞。这样通过控制有多少个"播种机",就可以控制大脑的结构了,这样可以缩小蛋的尺寸。
|
||||||
|
* 原则上Group遗传的一下代与父代是同一个播种(算法)类型,但不排除也有可能突变成另一个类型的Group。
