Efficient models

In the sense of “running as efficiently as possible”.

An application can often be described by various models that may exhibit fundamentally different performances in terms of memory and computing time. This is particularly important for large-scale models.

In this context, “running as efficiently as possible” applies to the part of the execution that is related to modeling, NOT to model design itself. In other words, this section does not explain how to write a better model that finds an optimal solution faster. Refer also to Performance and memory usage in The Language User's Manual.
