(class from pyomo.contrib.preprocessing.plugins.var_aggregator)
- class pyomo.contrib.preprocessing.plugins.var_aggregator.VariableAggregator(**kwds)[source]
Bases:
IsomorphicTransformationAggregate model variables that are linked by equality constraints.
Before:
\[\begin{split}x &= y \\ a &= 2x + 6y + 7 \\ b &= 5y + 6 \\\end{split}\]After:
\[\begin{split}z &= x = y \\ a &= 8z + 7 \\ b &= 5z + 6\end{split}\]Warning
TODO: unclear what happens to “capital-E” Expressions at this point in time.
