------=_NextPart_000_0005_01C2E1D0.6EE7FE20 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit ILOG was developing a common API for optimization problems 3 years ago. First, they have an optimization scripting environment called OPL studio. You could write a program that collects data, expresses constraints and an objective. Then, you could try it with different solvers and even to a limited degree create a hybrid solver. So, the OPL language is, in a sense, a common API. They did that before they came out with their common C++ API for all their solvers. That API is called Orchestra, I believe. Orechestra was a single API for expressing constraints, objectives, and heuristics. Then, you could try different solvers and even sequence them into hybrids. This is all done with elegant overloaded C++, so that pow(a,2) + pow(b,2) = pow(c,2) means something. So, no, it is not premature. It is possible. However, I can say with some assurance that ILOG invested heavily in the integration of these solvers. -David -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of Carl Tollander Sent: Monday, March 03, 2003 9:54 AM To: [hidden email] Subject: RE: [FRIAM] Re:Open Source for Optimization Algorithms This is good news.
