Hi, I am currently using CppAD which wraps IpOpt to compute the derivatives etc using AD and also call into IpOpt to set up and solve my IpOpt problem.

I wondered whether you have an example of AD being used with ifopt? If so which AD library(s) is compatible with ifopt?
Thanks

I am not sure if there is an example, but I believe as part of your constraint/cost you would use AD to calculate the jacobian when the method of your constraint/cost for providing the jacobian is called.
