GEODES

 
Approximates a minimum-length geodesic between two given endpoints in
multidimensional parameter space. Returns the shortest curve found as a
discrete set of parameter points ordered by arc length. Based on a relaxation
(iterative) solution of a boundary value problem for a nonlinear system of
ordinary differential equations. Developed by William L. Anderson of Elements
Research (elements@ix.netcom.com).
