Abstract: In performing a pattern search algorithm to find an optimal solution for an optimization, using a set of positive basis vectors that is non-maximal like a set of minimal positive basis vectors as search directions can sometimes causes the algorithm to converge at a non-optimal solution, like a horse saddle. The present invention provides a method to overcome this deficiency by rotating the vectors and hence increase the number of search directions.
Abstract translation: 在执行模式搜索算法以找到优化的最优解时，使用一组非最大像素的正基矢量像一组最小正基矢量一样作为搜索方向有时可能导致算法收敛于非最优 解决方案，像马鞍。 本发明提供一种通过旋转矢量来克服这种不足的方法，从而增加搜索方向的数量。

Abstract: A jack lift device for lifting and positioning loads includes a tube, a pipe and a hoist. The tube is configured to insert into a hole in a top of a step ladder. The tube is configured to couple to the step ladder so that the tube is positioned substantially vertically. The pipe is complementary to and selectively slidably positionable within the tube. A plate is coupled to and extends perpendicularly from an upper end of the pipe. A hoist is coupled to the tube and operationally coupled to the pipe. The plate is configured to position a load, such as a metal conduit. The hoist is positioned to selectively compel the pipe vertically through the tube so that the load that is positioned on the plate is positioned at a desired height, such as proximate to a joist to which the metal conduit is to be is coupled.
