GAMS Help-GAMS Programming Support

Example

Assisting in the translation of a real-world problem, like optimizing a supply chain, into a GAMS model by defining sets, parameters, variables, equations, and the objective function.

Scenario

A user wants to minimize transportation costs across a network of warehouses and retail stores. GAMS Help would guide through defining the problem in GAMS syntax, including how to represent transportation costs, constraints on supply and demand, and the optimization objective.

Example

Providing explanations for common GAMS error messages and tips for debugging models, such as issues with unbounded solutions or infeasibilities.

Scenario

When a user encounters an error stating 'Uncontrolled set entered as constant', GAMS Help can explain that this usually indicates a typo or a reference to an undeclared set and suggest checking the model's declaration section.

Example

Offering advice on improving the efficiency of GAMS models, such as using more effective solvers or tweaking model parameters for faster convergence.

Scenario

For a computationally intensive model, GAMS Help might recommend switching to a more efficient solver or modifying the model formulation to reduce solution time, ensuring that the user can find the optimal solution more quickly.
