ＧＳ算法在解决相位恢复问题的计算中有容易陷入局部极小困境的缺点，为克服这一缺点我们提出一种利用中间计算结果及一个加权因子λ来切换初始条件的新算法，该算法能够方便而随机地切换初始相位从而达到在一定程度上克服上述缺点的目的．计算实例表明了改进算法的效果． In order to overcome this shortcoming, we propose a new algorithm to switch the initial conditions by using the intermediate calculation result and a weighting factor λ, which can be easily used to solve the phase recovery problem. While the initial phase is switched randomly so as to achieve the purpose of overcoming the above disadvantages to some extent. The calculation example shows the effect of the improved algorithm.
