constraint optimization: solving large scale general nonlinear problems
Hi
I need advice regarding constraint optimization with large number of
variables.
I need to solve the following problem
max f(x1,...,xn)
x1,..xn
x1=g1(x1,...,xn)
.
.
xn=gn(x1,...,xn)
I am using Rdonlp2 package which works well until 40 variables in my
case. I need to solve this problem with over 300 variables. In this case
Rdonlp2 is very very slowly. I know
