Description

多样性保证了蚂蚁在觅食的时候不至走进死胡同而无限循环,正反馈机制则保证了相对优良的信息能够被保存下来。我们可以把多样性看成是一种创造能力,而正反馈是一种学习强化能力。正反馈的力量也可以比喻成权威的意见,而多样性是打破权威体现的创造性,正是这两点小心翼翼的巧妙结合才使得智能行为涌现出来了。

引申来讲,大自然的进化,社会的进步、人类的创新实际上都离不开这两样东西,多样性保证了系统的创新能力,正反馈保证了优良特性能够得到强化,两者要恰到好处的结合。如果多样性过剩,也就是系统过于活跃,这相当于蚂蚁会过多的随机运动,它就会陷入混沌状态;而相反,多样性不够,正反馈机制过强,那么系统就好比一潭死水。这在蚁群中来讲就表现为,蚂蚁的行为过于僵硬,当环境变化了,蚂蚁群仍然不能适当的调整。

既然复杂性、智能行为是根据底层规则涌现的,既然底层规则具有多样性和正反馈特点,那么也许你会问这些规则是哪里来的?多样性和正反馈又是哪里来的?我本人的意见:规则来源于大自然的进化。而大自然的进化根据刚才讲的也体现为多样性和正反馈的巧妙结合。而这样的巧妙结合又是为什么呢?为什么在你眼前呈现的世界是如此栩栩如生呢?答案在于环境造就了这一切,之所以你看到栩栩如生的世界,是因为那些不能够适应环境的多样性与正反馈的结合都已经死掉了,被环境淘汰了!
