xxx off doing sth

The cost from any node to the goal node can be estimated. This helps refine the search so that you're less likely to go off searching in the wrong direction.

 

这里的go off是一个组合词吗? 也可以这么理解吧

 

happen in a particular manner

同义词: come off , go over

后面的 searching in the wrong direction 就作为伴随状语了

但是xxx off doing sth的形式随处可见,这种用法具有普遍性,
如hold off doing sth,better off doing sth,虽然前面的xxx未必是同样词性
但这里可能是通过形式上的相近性生拼硬凑上去的,off在这里有不同含义
