A group of ellipsoidal invariant sets is designed off-line, and then constitutes a terminal constraint convex set whose coefficients are taken as on-line optimization variables.
通过离线设计一组椭圆不变集，并将其组合成一个终端约束凸集，其中凸集参数作为在线优化变量。

Some nonclassical potential symmetry generators and group-invariant of heat equation and wave equation were determined.
主要研究了热方程与波方程的非古典势对称群生成元及相应的群不变解。

Compared with the classical Lie method, it adds an invariant surface condition in the formation. Consequently, it makes calculation easy and obtains more group-invariant solutions.
