[Coin-ipopt] RE: Coin-ipopt digest, Vol 1 #35 - 1 msg

[Kirk Abbott]

Hello,

I am sure the Andreas can give some more reference,
But look out for:

Compute derivative and integral weight matrices for orthogonal collocation
using the subroutines given in J. Michelsen and M. L. Villadsen, Solution of
Differential Equation Models by Polynomial Approximation.

This is one of the key references.

In addition do a search on Beigler and collocation. They have done
some great work in this area.

There is a thesis by Min Oh (Modelling and simulation of combined
lumped and distributed processes, 1995, MIT) which is very readable
and can be used for implementation... it cuts to the chase and gives
the collocation matrices.

See also the thesis of Jeffrey Renfro (should be available from UMI).
A very nice piece of work. A well-kept secret is that at least 2
companies were spawned from this work!

Hope this helps.

Cheers,
Kirk.

Subject: [Coin-ipopt] help needed with DAE2NLP and DYNOPT


Dear Sir,

I am a Graduate Research Assistant, Dept of chemical
engineering at Lamar University, working on "Parallel
Optimization". 

I have downloaded the IPOPT and DYNOPT routines from
your website. We have a Nonlinear solver for NLP
problems. The 'DAE2NLP'
routine in your DYNOPT package will be very helpfull
to us for using with the solver which we have. Could
you please send me a 
documentation of how to use these subroutines to
convert DAE to NLP problem? 

In addition, It would be very helpfull for me if you
can send me some links which gives some theoritical
background in using 
orthogonal collocation for Dynamic optimization
problem. 

I would also like to try the Dynopt package. Could you
please send me some information on how to use that for
solving Dynamic
optimization problem?


Thank you,
Regards
Jay Chandrasekaran
