示例1: findPathA
int findPathA(cell start,cell end,path& best_path,tilemap& t_map, double (*h)(cell x,cell y) )
{
int width = 0;
int height = 0;
int is_ok = 0;

width = t_map[0].size();
height = t_map.size();
costmap G(height,std::vector<double>(width, infinite));
costmap F(height,std::vector<double>(width, infinite));
G[start.second][start.first] = 0;
F[start.second][start.first] = G[start.second][start.first] + dist_coeff*h(start,end);
std::set<cell > wawe;
std::set<cell > closed;
