Dealing with model is infeasible or unbounded error
Unfortunately, when modeling things hardly ever go as planned at the first try and more than once you end up with results that you did not expect. At first glance…
Getting multiple solutions from the solver
Some of the solvers in AIMMS, including the CP Optimizer solver for Constraint Programming problems, support not only returning a single (optimal) solution, but also a pool of feasible solutions….
Creating StopWatch in AIMMS to time execution
There are situations where you would like to know how long the execution of something in AIMMS took. When you are working as an AIMMS developer, one of the tools…
Exporting a section and importing it in another AIMMS project
Sometimes there are parts of a model that you would like to re-use in another AIMMS model. If it is a very generic component, you could choose to create an…
Using GMP functions instead of regular solve statement
In the simplest form solving a Mathematical Program identifier is done by using the intrinsic solve statement of AIMMS: solve MathProgram ; For the majority of the AIMMS modelers, this…
Getting value of a dynamic identifier
With the addition of Model Edit Functions (MEF) to AIMMS 3.11, a lot of things that were previously impossible to do with AIMMS became possible. One simple example of something…
