The ipopt-hs package
- needs the c library ipopt installed. Also by default a binding to nlopt is included. Nlopt by default does not include shared libraries, which seems to be needed to run things from ghci (ie. you need to ./configure --enable-shared when buildin nlopt).
A embedded language, similar to the one provided by glpk-hs, is defined in Ipopt.NLP. The goal is to define problems at a level similar to other algebraic modeling languages, but retain some of the safety and flexibility available in haskell. There is some overhead http://code.haskell.org/~aavogt/ipopt-hs/examples/bench.html but at least on the small 4-variable constrained optimization problem.
Current limitations include:
copying in every iteration happens between between Data.Vector.Storable and Data.Vector might be avoidable somehow. Currently it is done because AD needs a Traversable structure, but Storable vectors are not traversable.
sparseness of derivatives isn't used
no binding to SetIntermediateCallback
