WebIn this paper, we discuss the computational complexity of the following enumeration problem: given a rational convex polyhedron P defined by a system of linear inequalities, output each vertex of P. It is still an open question whether there exists an algorithm for listing all vertices in running time polynomial in the input size and the output size. Webmethods trade precision for scalability via a convex relaxation of ReLU outputs. The most precise convex relaxation of ReLU output is based on the convex hull of Polyhedra [20] which is practically infeasible as it requires an exponential number of convex hull computations, each with a worst-case exponential complexity in the number of neurons.
WebThe polyhedra are either given as the convex hull of a set of points plus (possibly) the convex cone of a set of vectors, or as a system of linear equations and inequalities. The name PORTA is an abbreviation for POlyhedron Representation Transformation Algorithm and points to the basic function 'traf'. WebMay 8, 2024 · 5.

WebMar 24, 2024 · A convex polytope may be defined as the convex hull of a finite set of points (which are always bounded), or as a bounded intersection of a finite set of half-spaces. Coxeter (1973, p. 118) defines polytope as the general term of the sequence "point, line segment, polygon, polyhedron, ...," or more specifically as a finite region of n-dimensional … http://homepages.math.uic.edu/~jan/mcs320/mcs320notes/lec31.html
