#214: in which order are auxiliary variable definitions stored ? --------------------------+------------------------------------------------- Reporter: michel | Owner: michel Type: bug | Status: new Priority: blocker | Milestone: 4.3 Component: Preprocessor | Version: Keywords: | --------------------------+------------------------------------------------- DynamicModel.cc:3787 and 3848, new definitions are inserted in front of the deque ModelTree.cc:1382, new definition is pushed in the back of the deque 1) The order of the definitions matters because, for example, a conditional expectation lagged by 2 periods is built on the basis of the auxiliary variable for the lagged expectation by 1 period. 2) StaticModel.cc:1707 and 1735 write the equations in the wrong order when equations are inserted in front of the deque There are other problems related to the handling of auxiliary variables in the *.m files, when computing the steady state of models with auxiliary variables, see ticket 213. -- Ticket URL: <https://www.dynare.org/trac/ticket/214> Dynare <http://www.dynare.org> The Dynare project
#214: in which order are auxiliary variable definitions stored ? --------------------------+------------------------------------------------- Reporter: michel | Owner: michel Type: bug | Status: new Priority: blocker | Milestone: 4.3 Component: Preprocessor | Version: Keywords: | --------------------------+------------------------------------------------- Comment(by sebastien): The aux vars in DynamicModel::substituteLeadLagInternal() and DynamicModel::substituteExpectation() are added in front of the deque. The order is taken care of, but of course a bug cannot be ruled out. The ModelTree::addAuxEquation() method (which adds at the back of the deque) is only used when cloning a ModelTree or converting a DynamicModel to StaticModel, in order to keep the order during the cloning/conversion. Concerning the bug that you mention in StaticModel, can you be more specific or give an example? Also in that case I have taken care of the order (subject to the same disclaimer). -- Ticket URL: <https://www.dynare.org/trac/ticket/214#comment:1> Dynare <http://www.dynare.org> The Dynare project

I have made the necessary change. I still need to test. -- Ticket URL: <https://www.dynare.org/trac/ticket/214#comment:2> Dynare <http://www.dynare.org> The Dynare project

Also breaks the testsuite's Makefile (fix in aa1306651d20205cadf5a8a09c093fc7b3d3dd1a). The fix for size of ys_ still needs to be ported to 4.2. -- Ticket URL: <https://www.dynare.org/trac/ticket/214#comment:3> Dynare <http://www.dynare.org> The Dynare project
