Methods for exploiting hyper-sparsity in the revised simplex method
Methods for exploiting parallelism in the revised simplex method
Simplex-like methods which exploit parallelism when solving large scale linear programming problems (in collaboration with Ken McKinnon and supported by EPSRC research grant GR/J0842).
EMSOL is a mathematical programming package based on my revised simplex method solver.
LP Explorer is a java applet designed by me and Melanie Baird (Sellic On-Line) who actually wrote it.
