The codes were taken from the 2nd edition of my book Compact Numerical Methods for Computers, where they are in Pascal. They were converted by p2c to c, so are pretty opaque and likely difficult to modify. Moreover, they are based on 1970s codes I wrote for the first edition. Why not look at optimr (CRAN) or the more extensive optimrx (R-forge) where there are calls to pure R versions with improvements in the codes as well as bounds constraints on parameters for some. If you have suggestions or queries about the newer codes, contact me off-list and we'll see what can be done.
