摘要
建立了梯度法的开关电容电路结构，分析了最速下降法、牛顿方法和拟牛顿法的共同特点，研究无约束差分优化的开关电容电路结构。通过计算机仿真实例，证明了该电路收敛速度较快，且随着有关参数的改变，可在不同初始条件下达到各自的局部最小值；许多情况下，该电路可以避免一些局部最小值，而找到一个全局最小值。
Switched capacity circuit structures of gradient methods are proposed,the common properties of the steepest descent method, Newton method and quas Newton methods are analysed. Switched capacity circuit structures for unconstrained differential optimization are investigated. By the actural examples of computer simulations, it is verified that these circuit structures provide better convergence properties. Furthermore, changing the relevant parameters can reach different local minima from the different initial conditions. In most cases, these circuit structures may avoid some local minima and find a global minimum.
