代数 示例 2x2+3y2=62x2+3y2=6 将每一项除以66以使方程右边等于一。 2x26+3y26=662x26+3y26=66 化简方程中的每一项,使右边等于11。椭圆或双曲线的标准形式要求方程的右边为11。 x23+y22=1x23+y22=1
Chapter 7 Vertex Finding Abstract Vertex finding is the search for clusters of tracks that originate at the same point in space. The chapter discusses a variety of methods for finding primary vertices, first in one and then in three dimensions. Details are given on model-based clustering, the...

in time O(nk/2+2) and polynomial space, and in time O(1.6181n) and polynomial space. Note that the FPT algorithm of Guillemot and Marx [34] cannot be adapted for the counting version. In fact, we argue (§ 5) that a running time of the form nO(k) is almost best possible and...
Under a Creative Commons license Open accessAbstract Form-finding is a process in architectural design. Architects create and manipulate the morphology of a building by finding the form using digital tools and algorithms, such as machine learning. Recent research indicates that existing machine learning...
