In general I use most references to give me a look at how others have
solved the problem. Numerical Recipes often has useful information to
help optimize the code further. I haven't read Plaugers latest, but I
am sure it is quite good. I just didn't think of his. I also use a
very nifty (but old) book called by Robert Garfinkel and George L
Nemhauser. It was published by Wiley in 1972, but is one of those
volumes that is sort of a standby for me.
