Memory usage is kept nearoptimal as buffer memory becomes allocated only when necessary and is freed as soon as possible, thus minimizing memory leaks.
内存使用将保持接近最优状态，因为缓冲区内存仅在必要时才分配，并且会尽快释放，从而最小化内存泄露。

The result shows that it does not demand to presuppose the initial parameters nearoptimal solution and it is more efficiency than the conventional optimization method.
结果表明，该方法不要求预先假定接近最优解的初始参数值，且比传统优化方法有效。

The protocol can search multiple feasible tree branches, and select the optimal or nearoptimal branch for connecting the new receiver to the multicast tree if it exists.
