Abstract
We provide two algorithms for computing the volume of the convex polytope Ω : = { x ∈ ℝ n + | Ax ≤ b }, for A , ∈ ℝ m × n , b ∈ ℝ n . The computational complexity of both algorithms is essentially described by n m , which makes them especially attractive for large n and relatively small m , when the other methods with O ( m n ) complexity fail. The methodology, which differs from previous existing methods, uses a Laplace transform technique that is well suited to the half-space representation of Ω.Keywords
