Three Steps of HGM

  2. Finding a holonomic system satisfied by the normalizing constant. We may use computational or theoretical methods to find it. Groebner basis and related methods are used. -
  3. Find an initial value vector for the holonomic system. +
  4. Finding an initial value vector for the holonomic system. This is equivalent to evaluating the normalizing constant and its derivatives at a point. This step is usually performed by a series expansion. -

  6. Solving the holonomic system numerically. We use several methods in numerical analysis such as the Runge-Kutta method of solving ordinary differential equations and efficient solvers of systems of linear equations. @@ -109,22 +162,32 @@ of the OpenXM documents or in this folder. -The nightly snapshot of the asir-contrib can be found in the Asir-Contrib page below, +The nightly snapshot of the asir-contrib can be found in the asir page below, or look up our cvsweb page.
