WebOne such algorithm is the Wavefront or Grassfire Algorithm. Set-Up This algorithm starts with a grid representation of the environment (2D array). In this grid, obstacles are marked with a value of -1 to indicate they are nonnavigable. Zeroes indicate unexplored or possibly unreachable positions. Web第二个问题是，您返回的是函数指针，标准不保证从函数指针到void*的转换。这里的替代方法是返回适当类型的函数指针，即std:：vector或使用更高级别的构造，如std:：function C++11或C++03:std:：vec中的boost:：function第一种方法更适合您提供的描述，因为函数的类型似乎是固定的，并且使用函数指针的开销 ...
