[Coin-discuss] Modeling Language

[Alan King]

My list for desireable propertes of a COIN AML package:

Philosophy:
1)  Compatibility.  Able to use your favorite AML language or package on 
the front end, and favorite solver on the back end.
2)  Open source.  Source code level access to the parser input and output 
methods and data structures.
3) Utility and extensibility.  Able to incorporate new features and 
technologies of interest to the community, eg document processing and web 
services standards.

Functionality:
a)  Support multiple flavors of output methods.  Eg C++, Java source code 
emitters.
b)  Distributed construction of model data for distributed solution of 
optimization problems.
c)  Interface to other modeling paradigms, eg simulation, statistics, etc, 
using AML namespaces.
d) Model debuggers, anyone?

Re: [Coin-discuss] Modeling Language







Well, count me in as being interested! 

Let's begin.  Here are my thoughts for next steps: 

1) Make a list of what's available.   Eg, we have already some good 
suggestions: 
======================================= 
*) GNUMathProg language http://www.gnu.org/software/glpk/glpk.html

*) Zimpl http://www.zib.de/koch/zimpl/ 

*) FLOPC http://www.mat.ua.pt/thh/flopc/ 

*) and AMPL's possible release under open source license. 
======================================== 

1a) Investigate each one and post a brief write up. 

2) Make a list of desirable properties for an open source AML package. 
2a) Match this list against available solutions and make some conclusions 

3) Host a design discussion 

4) Set priorities and make a plan.

What I'm really trying to ask is:  Is there any plan or interest to
build an open source modeling language and compiler system like GAMS?
