NEOS has been used extensively for a variety of applications, including modeling electricity markets, predicting global protein folding and training artificial neural networks.
Using flexible combinations of World Wide Web tools, remote procedure calls and email, researchers can access the NEOS server and have their optimization problems solved automatically, without installing software, downloading and linking code, or writing driver subroutines. Users of NEOS can obtain a solution in a matter of hours instead of days.
“Because of its ease of use and generality, NEOS has gained tremendous popularity,” said Jorge Moré, an Argonne Distinguished Fellow who has guided the development of NEOS since its inception a decade ago. In 1999, there were fewer than 18,000 submissions to NEOS. Today NEOS is the premier source of optimization technology on the Web for users of optimization software, with over 235,00 submissions in 2009.
Using the NEOS server is easy. The user selects a program, or “solver,” for a particular type of optimization problem. In order to help with the choice, an “optimization tree” provides suggestions, and each solver comes with sample problems and background information. Once the user has selected the solver, NEOS compiles all subroutines, links with the appropriate libraries, and carries out the necessary computations. The user is then sent the solution, along with various runtime statistics.
The two million milestone also reflects the growing use of the NEOS server by students and faculty in both undergraduate and graduate classes.
“By providing free access to the most recent and best optimization software, NEOS enables students to experiment with a broad variety of solvers and to attack problems substantially larger than typical classroom examples,” said Todd Munson, an Argonne computer scientist who has been an architect of NEOS. “This use provides a strong and lasting foundation for future optimization research.”
The NEOS team, consisting of Moré, Munson, Liz Dolan (a graduate student working at Argonne), and Bob Fourer (their colleague at Northwestern), won the prestigious Beale-Orchard-Hays Prize in 2003 for excellence in computational optimization. In presenting this prize, which is awarded only once every three years, the Mathematical Programming Society noted: “The NEOS Server has had a tremendous impact in the field of optimization. The influence of NEOS is such that in many applied fields the NEOS Server is synonymous with optimization.”
The NEOS Server is operated with support from DOE. For more information about NEOS, please visit the web site: www-neos.mcs.anl.gov.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
