<div>The [https://projects.coin-or.org/OS Optimization Services (OS)] is one of the [http://www.coin-or.org/index.html COIN OR] projects. OS provides a set of XML-based standards for representing optimization instances ([[OSiL]]), optimization results (OSrL), optimization solver options (OSoL), and provides a framework for communication between clients and solvers in a distributed environment using Web Services.<br />
<br />
The OS project directly supports the following solvers:<br />
<br />
*Bonmin<br />
*Cbc<br />
*Clp<br />
*Cplex<br />
*DyLP<br />
*Glpk<br />
*Ipopt<br />
*Lindo<br />
*SYMPHONY<br />
*Vol<br />
<br />
If we hook ASCEND to OS and produce [[OSiL]] instances for the models written in ASCEND we would be able to take advantage of the solvers supported by OS and also of next generation distributed optimization systems, mainly optimization over the Internet.</div>Akshayhttps://ascend4.org/index.php?title=OSiL&diff=662OSiL2010-05-25T14:09:16Z<p>Akshay: Created page with 'Optimization Services input instance Language (OSiL) is an XML-based language for representing instances of large-scale optimization problems.OSiL is highly extendible and presen…'</p>

<div>Optimization Services input instance Language (OSiL) is an XML-based language for representing instances of large-scale optimization problems.OSiL is highly extendible and presently supports the following optimization types :<br />
<br />
* Linear<br />
* Mixed integer<br />
* Bound constrained optimization<br />
* General quadratic optimization<br />
* Multi-objective optimization<br />
* Nonlinear unconstrained/constrained<br />
* General mixed integer nonlinear<br />
* General nonlinear with user-defined functions<br />
* General nonlinear with xml data (either locally within the OSiL or remotely located)<br />
* General nonlinear with data look up (XPath)<br />
* Constraint/logic programming<br />
* Complementarity problem<br />
* General nonlinear with simulations (black-box functions)</div>Akshay
