Volume and integration on a convex polytope
I have developed a (recursive) program to compute the exact volume of a
convex polytope in R_n, given by its defining hyperplanes Ax<=b.
The underlying method is based on Euler's identity for homogeneous functions.
In the same vein we have also provided a method for integration of homogeneous functions
on domains also defined by homogeneous functions.

volume of a convex polyhedron in Rn", J. Optim. Theor. Appl. 39

Our volume algorithm is one of those implemented in the public software
VINCI. which itself the volume
computation module of
polymake, a tool for the algorithmic treatment of convex
polyhedra, developed in the Discrete Geometry group
at the Institute of Mathematics of Technische Universitat, Berlin.
This volume computation occurs in various applications in
Economics, computational complexity analysis, linear systems modeling,
VLSI design, Statistics .... In particular, our volume algorithm (as well as our integration method for homogeneous functions) has also been used
as a brick element in the "natural element method" (NEM), a relatively
recent method for solving partial differential equations, as well as in recent extensions
of finite element methods (X-FEM) for some boundary value problems involving
discontinuities. In the X-FEM, the finite element mesh need not conform to the internal boundaries (cracks, material interfaces, voids, etc.), and hence a single mesh suffices for modeling as well as capturing the evolution of material interfaces and cracks in two- and three-dimensions. Our volume (and integration) algorithm is used in e.g.:

My colleague Didier
and I, have developed a software called
for the global minimization of a multivariate polynomial
on a semi-algebraic set. This software was among 30 softwares
selected (out of 160) as finalists of the
software competition in Switzerland (September 2004).
The underlying method makes extensive use of recent results from real
algebraic geometry on the representation of polynomials,
positive on a compact semi-algebraic set. For more details, see:

POCP is a free Matlab package developed by Didier Henrion, myself and Carlo Savorgnan. It uses GloptiPoly 3, and, optionally, YALMIP. The goal is to help solving nonlinear optimal control problems for which all the problem data are polynomial. POCP reformulates such control problems as an instance of the generalized problem of moments to which one applies a hierarchy of semidefinite relaxations.
