Have a look at the following R-help entry in March:
https://stat.ethz.ch/pipermail/r-help/2008-March/157249.html
with an example of how to use 'optim' with equality constraints. This will
also work with no gradient and 'method="SANN" '.
In my experience, solutions received with "SANN" were
Dear All,
I am having trouble in using R function "constrOptim" to do constraint
optimization. It seems that "constrOptim" calls function "optim" when it
does the optimization, and "optim" allows us to set "method" to be "SANN"
if we want to use simulated annealing. In "optim", the function all
