At this point, the atomic group will kick in. The engine will discard all backtracking positions.

此时，最小组团就发挥作用了：正则引擎会放弃所有回溯位置。

An algorithm is presented for complex maze by marking shortest path between the start point and current exploring point with recursive backtracking.

用标记每个搜索位置离起始位置最近距离的方法，通过递归函数求解，提出了一个对复杂迷宫的简明求解算法。

However, it does mean backtracking another four days back to your start point unless you take one of the sneaky shortcut options.
