Energy Functions for Knots: Beginning to Predict Physical Behavior (text and tables only; figures separate below)
A complicated unknot (pdf file)
that is an elaboration of an example suggested by M. Freedman. Wu's program MING succeeds
in untangling this, as does Evolver. By combining Umd-energy minimizing flow with
shrinking and eliminating edges, Wu has produced examples of tangled, but unknotted, polygons that
appear to be local minima for Umd.
