規(guī)則介紹
基于二維元胞自動(dòng)機(jī)的生命游戲可視化實(shí)現(xiàn)
規(guī)則：藍(lán)色方塊代表生命
- 有顏色的方塊代表生命，無(wú)顏色的方塊代表死亡
-
一個(gè)細(xì)胞周圍有八個(gè)細(xì)胞，對(duì)于一個(gè)活細(xì)胞來(lái)說(shuō)，如果它周圍的八個(gè)細(xì)胞中：
如果只有一個(gè)或沒(méi)有一個(gè)是活的，那這個(gè)細(xì)胞就會(huì)死亡
如果其中兩個(gè)或者三個(gè)細(xì)胞是活的，那這個(gè)細(xì)胞就能維持生命
如果超過(guò)3個(gè)細(xì)胞是活著的，那這個(gè)細(xì)胞就會(huì)因?yàn)檫^(guò)于擁擠而死亡 - 對(duì)于一個(gè)死細(xì)胞來(lái)說(shuō),如果這個(gè)細(xì)胞周圍如果有三個(gè)細(xì)胞存活,該將獲得新生。
附：所有規(guī)則都可以修改，種群初始密度也可以修改。本實(shí)驗(yàn)采用初始化人口隨機(jī)分布，也可以自定義初始化人口分布以及網(wǎng)格大小得到滑翔機(jī)，播種機(jī)等復(fù)雜美觀圖形。

''' demoName：life simulation game principle: cellular automata (two dimensional) the rule of the game ： 1. colored cell represents life, uncolored cell represents death 2. a cell has eight cells around it, to a live cell: 2.1 if only one or none of them are live, the cell will die 2.2 if two or three of them are live, the cell will sustain life 2.4 if more than three of them are live, the cell will die 3. to a dead cell, if there are three alive around it ，the cell will gain life '''
