Speeding up DSI with an algebraic multigrid method

@inproceedings{Jerome2001a,
 abstract = { The current speed of convergence of DSI is directly linked to the ratio between the
number of constraints and the number of nodes of the interpolated object. If this ratio is
high, the best approximate solution is quickly reached. If it is low, DSI converges slowly. To
speed up the convergence, the resolution of the local equation of DSI is modi¯ed by adding
an algebraic multigrid method. This method, applicable to any Gocad object (atomic or
gridded), is extremely fast as it has the advantage to speed up the DSI convergence: The
number of iterations is then no longer dependent on the mesh size. },
