贪婪算法是一种对某些求最优解问题的更简单、更迅速的设计技术，对范围相当广泛的许多问题他能产生整体最优解或者是整体最优解的近似解-Greedy algorithm is an optimal solution for some problems simpler, more rapid design techniques for a wide range of many of the problems that he could produce an overall optimal solution or the approximate solution of the overall optimal solution
