When propagating light\|ray passes through two fixed points in the gradient index mediums and a cuspidal variable\|point （at this point the trace equation of propagating light\|ray is non\|differentiable） at the borderline of two different GRIN mediums, the mathematical relationship, which the trace equation of propagating light\|ray and borderline equation of two different GRIN mediums should satisfy, is derived by the Fermat's principle and calculus of variation.

当光线通过梯度折射率介质中两个固定点和两个GRIN介质界线上的可动尖点（光线轨迹方程的不可微点）时，由费马原理和变分法运算推得传输光线的轨迹方程与两种不同GRIN介质的界线方程应满足的微分关系式。

At the time of dealing with the fourth problem, we try calculus of variation of spending, move route transform into a line issue of the victory, Utilize Euler formula , ask and publish time running orbit after a little while most , confirm right route most, It's a pity that we can't get a satisfactory answer in a short time.

得到如下结果：在水流速度不变的情况下，年第一名的游速为，与方向与X轴成，如竞渡者以行进，则与X轴成，用时分秒，竞渡者若与对岸垂直游不可能达到终点；在不同区段内水流速度不变的情况下，竞渡者以折线前进，用时约为；在同一区段内水流速度变化情况下，竞渡者以曲线前进，用时约为。

On this basis, anoptimization algorithm library named OPTLIB is formed. The study of dynamic optimization theory is followed. To solve the problem of thecoupling of the static and the dynamic parameters of the flying vehicle design, some auxiliaryvariables are introduced to deal with them together. Then the calculus of variation is adoptedand augment form of Pontryagin's Maximum Principle is derived.

研究了飞行器设计中的典型动态优化问题——轨迹优化问题及算法，针对飞行器设计中的静态参数和动态参数互相耦合的问题，引入辅助变量将静态参数和动态参数统一处理，在此基础上用变分法推导了极大值原理的增广形式，证明了单独的静态或动态最优并不等于总体最优。
