In AIMMS 24.6 a new implementation for the generation of a mathematical program has been introduced. This implementation is not yet complete with respect to all the features that may be present in a mathematical program. By default, the new generator will attempt to generate the model, but only for LP and MIP models. If the new generator fails for some reason, the generation stops and falls back to the old way of generating. You will get warning messages containing the reason(s) why the generation was not done by the new generator. If there is not an easy way to work around the unsupported feature(s) it is better to not let the new generation try, and thus just rely on the old generation. Setting this option to ‘On’ will disable the new generator.
Possible values are:
On
Off
Currently, the old generator will always be used:
For a mathematical program that is not an LP or MIP.
For generating a robust or stochastic model via the GMP functions
GMP::Instance::GenerateRobustCounterpartorGMP::Instance::GenerateStochasticProgram.If one of the constraint or variable definitions contains a (rare) expression that is not yet supported by the new compiler.
Note
In some cases the new generator handles frozen variables differently compared to the old generator. If the options Equal Bounds Imply Nonvar and Move Nonvar Level Within Bounds are switched on then the new generator behaves more like the old generator.
