Abstract: Optimization problem in finite or infinite feasible scheme selection optimization program.Newton's method in optimization problems are widely used and in solving optimization problems has certain advantages.Study on the properties and characteristics of Newton's method,has the choice for the optimization of related problems.For example,Newton's method in the Nonlinear programming,according to the problem of the characteristic,the appropriate application in actual life,use optimization method for our production life to bring the convenience.
Keywords: Newton's method; Nonlinear programming; Gauss-Newton method; Nonlinear least squares
现实生活中,常常遇到如何设计或求解最优化问题.例如,如何将有限的资源在不同的部门分配,使得方案达到最佳,即获得最好的经济效益;农作物生产安排时,如何布局才会使农田发挥地区优势,稳定高产;军事作战时,怎样确定作战方案,才能以最小的代价夺取最大的胜利;工程设计中,如何选择参数才能使方案既满足各项要求,又使成本最低.
