LINDO Systems announces performance enhancements, new features

LINDO Systems recently announced a wide range of performance enhancements and new features for What’sBest!, LINDO API 11 and LINGO 17 that include:

  • Faster solutions on linear models with improved simplex solver. Enhancements to the Simplex solvers boost performance on linear models. Large models solve an average of 20 percent faster using primal simplex and 15 percent faster for dual simplex.
  • Improved integer solver. New symmetry detection capabilities dramatically reduce the time required to prove optimality on certain classes of models with integer variables. Performance has been improved on Markowitz portfolio problems with minimum buy quantities, and/or limit on number of instruments at nonzero level. Other enhancements provide faster solutions on certain task assignment-like models.
  • Global solver enhancements. Stability and robustness of the Global solver has been improved through several enhancements to quadratic recognition and range reduction. Improved exploitation of convexity of certain ratio constraints, e.g., as found in heat exchanger network design problems.
  • More constraint types supported. Several new functions and constraint types are recognized, e.g., the AllDiff constraint for general integer variables. AllDiff constraints allow one to specify a set of integer variables, such that each variable in the set must have a unique value, different from all other variables in the set.

Electoral College put to the math test


With the campaign two months behind us and the inauguration of Donald Trump two days away, isn’t it time to put the 2016 U.S. presidential election to bed and focus on issues that have yet to be decided? Of course not.

Gartner: AI technologies to be pervasive in new software products

Market hype and growing interest in artificial intelligence (AI) are pushing established software vendors to introduce AI into their product strategy, creating considerable confusion in the process, according to Gartner, Inc. Analysts predict that by 2020, AI technologies will be virtually pervasive in almost every new software product and service. Read more →

Drone delivery: Professor develops solution to minimize delays in operations

When delivery companies like FedEx, Amazon and UPS launch drones to deliver packages in the near future, one Kennesaw State University computer science professor may be at the crux of solving one of its most complicated problems. Donghyun (David) Kim, assistant professor of computer science and an expert in computer algorithm optimization, is designing a fast-running algorithm to tackle simultaneous coordination problems among multiple delivery trucks and the drones launched from them.

Tech spending growth limited to about 5 percent through 2018

Forrester predicts U.S. business and government tech spending will continue to grow by 4.8 percent through 2017 and increase to 5.2 percent in 2018. While these forecasts are higher than Forrester’s projections following the 2016 presidential election, they are lower than the expected numbers from a year ago. Read more →
