Does anybody have code to do a better job of solution than the standard Feynman small-interval method? Preliminary results of mine indicate that that method takes prohibitively long for accurate results, and I'm wondering about variable-step algorithms. My ultimate goal is a Thinglab-like system for throwing planets and stars around, running on a Sun workstation, which makes a fun toy for such problems. Anyone have any suggestions?
