We are happy to announce a new section "Optimization Software" for our journal "Optimization Methods and Software" (OMS). The section will be edited by Tamas Terlaky.
The objectives of the new section are: to facilitate high level software developments; to inform the optimization community about these new developments; to make codes available to the optimization community, and, to develop new ideas and new optimization software tools. The software section of OMS will publish papers that scientifically document novel programs and software packages appropriate to solving optimization problems, or that describe components in more complex software.
Each paper will be refereed to ensure: novelty, quality of presentation, availability of software and potential to meet the needs of the optimization community. The software section will publish papers in the following three categories: primary papers of 10-15 pages, which describe a class of problems, the methodology to solve such problems and document the implantation and the power of the authors software package; survey papers of 15-20 pages which survey and evaluate the available software packages for a class of optimization problems, and, short communications of 5-10 pages, which document specific improvements in methodology or implantation technology of an important algorithmic element of optimization software.
In addition to the standards as title, authors names and address (including e-mail), abstracts and keywords, each paper should include a clear definition of the problem class, exploring methodology and implementation documentation, test set definition and evaluation, relevant literature, and, where appropriate, information on how to obtain the software and whether it is public domain or (semi)commercial.
Software that is related to papers published in the software section of OMS and made publicly available by the authors will be included in the OMS collection of optimization software. Upon agreement, this software will be published on the OMS-CD together with the written paper.
Papers and software for the OMS software section, preferably based on Windows PC, HP, Sun UNIX or LINUX standards, should be submitted directly to the software editor to the following address:
OpenGL for Fortran
90
Recently the OpenGL Architecture Review Board approved the Fortran 90 bindings for the OpenGL 2D and 3D graphics library. These bindings are defined in NISTIR 6134 "A Fortran 90 Interface for OpenGL: Revised January 1998", which is available at the web site below.
I am pleased to announce the availability of f90gl version 1.1, a public domain implementation of the OpenGL Fortran 90 bindings. This version implements the interface for OpenGL 1.1 (or Mesa), GLU 1.2, GLUT 3.6 and several OpenGL extensions. It supports most Unix workstations and Windows 95/NT.
OpenGL is a software interface for applications to generate interactive 2D and 3D computer graphics. OpenGL is designed to be independent of operating system, window system, and hardware operations, and is supported by many vendors. The OpenGL Fortran 90 bindings represents a significant development for scientific visualization in the Fortran community. Until now there has never been an industry standard for generating graphics from Fortran programs; instead, only proprietary libraries that support a limited number of systems have been available. With the new bindings, a Fortran programmer can write standard-conforming graphics applications that will be portable over most computing platforms.
More information and the f90gl package are available at the f90gl web page.

disponível: AMPL Optimization Solvers on NEOS
We have installed several solvers on NEOS that accept problems in AMPL, a mathematical programming language that is suitable for rapid prototyping and model development. For more information on AMPL, see http://www.ampl.com/cm/cs/what/ampl/
The DONLP2, LANCELOT, LOQO, MINOS, and SNOPT solvers can be found at
http://www.mcs.anl.gov/otc/Server/
This page also has a pointer to the AMPL-PRO interface, which allows users to submit a problem to all the solvers. Each solver has instructions on how to submit a problem using AMPL, as well as pointers to a user guide and a set of sample problems. For examples of models in AMPL format, see
http://www.netlib.org/ampl/models
Credit for installing these solvers is due to
