这句话是什么意思啊？并分析句子的结构及成分

AJ who put his mind to comprehending sth that unorthodox ever to have been invented through their own mathematic simulations

Answer 1

The first two letters "AJ" is meaningless.
then this stentence means that : sth is the most unorthodox had been ever invented, this unthordox thing was invented through some mathmetic simulation, AJ is trying to understand this most unorthordos thing,
这句话的意思是AJ 正在集中精神去试图理解这个通过数学上的模仿而建立的神秘物体。
这句话里who 引导一个句子做主语的同位语，像one who...这样，sth后面的that引到一个句子做sth的表语，对sth的具体内容进行解释说明，而unorthodox是做that的表语，这里省略了谓语动词is，即that （is） unorthodox ever...后面through所引导的成分做invented的伴随状语，用作说明invented的具体方式。

本来应该解释为他试图通过模仿来理解这个有史以来最异端的东西，但是后面的their与前面的his mind不搭配，所以只好解释成上面一种......
