The direction of search starting from an extreme point is a convex combination of all descent directions along the edges at the point.
从极点出发的搜索方向是该点处所有下降棱方向的一种凸组合。

In this paper, we propose a new descentdirection. Under the pseudomonotone of the underlying function, we prove the global convergence of the algorithm.
提出一个新的下降方向,在函数伪单调的条件下证明了算法的全局收敛性。

This method proposes five decimation patterns based on the gradient descentdirection, and it can select the decimation pattern adaptively during the motion estimation.
