ODH|CPLEX Solver Webinar

Speaker(s): Robert Ashford, Published: 05 May, 2021

GAMS/ODHCPLEX is a solver from Optimization Direct Inc. that implements a set of heuristic methods (named ODHeuristics) for finding feasible solutions to Mixed Integer Programming (MIP and MIQCP) models that uses IBM CPLEX as its underlying solver engine. It is designed for large-scale models which a MIP solver would find intractable: either by it being unable to find feasible solutions at all or; more usually, by being unable to find feasible solutions of adequate quality in the time available to its user.

SHOT Webinar

Speaker(s): Andreas Lundell and Jan Kronqvist, Published: 15 Apr, 2021

SHOT (Supporting Hyperplane Optimization Toolkit) is a deterministic solver for mixed-integer nonlinear programming problems (MINLPs). Originally, SHOT was intended for convex MINLP problems only, but now also has functionality to solve nonconvex MINLP problems as a heuristic method without providing guarantees of global optimality. However, SHOT can solve certain nonconvex problem types to global optimality as well.

Informs 2020 Workshop - Part 3: solving models in the cloud with GAMS Engine

Speaker(s): Frederik Proske, Published: 17 Nov, 2020

In November 2020, we hosted a virtual workshop at the Informs Virtual Conference. The Workshop was split up into three parts about GAMS, GAMS MIRO and GAMS Engine. In this third part of the workshop Freddy explains what GAMS Engine is, and demonstrates the various ways to interact with Engine, especially how to use the Python API to solve a typical two part energy model with an “Invest” and a “Dispatch” component.

Informs 2020 Workshop - Part 2: Model Deployment with MIRO

Speaker(s): Frederik Proske, Published: 17 Nov, 2020

In November 2020, we hosted a virtual workshop at the Informs Virtual Conference. The Workshop was split up into three parts about GAMS, GAMS MIRO and GAMS Engine. In this second part of the workshop Freddy explains how to turn a model into a GAMS MIRO app and how to deploy it.

Informs 2020 Workshop - Part 1: Introduction to GAMS

Speaker(s): Stefan Mann, Published: 17 Nov, 2020

In November 2020, we hosted a virtual workshop at the Informs Virtual Conference. The Workshop was split up into three parts about GAMS, GAMS MIRO and GAMS Engine. In this first part of the workshop Stefan explains the benefits of GAMS and demonstrates how to implement and solve a simple optimization problem.

GAMS MIRO Engine - running GAMS in the cloud!

Speaker(s): Hamdi Burak Usul, Published: 02 May, 2020

GAMS MIRO Engine is a new, highly scalable version of GAMS that is tailored to cloud environments. MIRO Engine moves the heavy computation away from local PCs to servers and takes care of distributing your optimization jobs. It scales up or down depending on the workload. With the built-in user management system, you can limit user activities to reflect your organizational hierarchy.
