Specifically I can see that the litterature mentions's "Scarf's algoritm" (Scarf 1967) and Merril's refinement of Scarf's algoritm in 1972, but there might be other algoritms too...

I'm about to write my thesis in economics and will need to setup and solve a system of non-linear equations. At our university we usually use GAMS for this, and though GAMS is a fine program, it bugs me a that I won't be able to run my code after I finish my thesis without buying a license for the program(about $3.500 :-(( )
So I've looked around for NL-stuff for R, but I can't find anything. The closest thing appears to be optim(), but it doesn't seem to allow constraints(as in fn = constant) or equations systems. So, anyone knows if there is a method in R that you can use for this purpose?
