This triggers some of the inequality chaining logic (this is deep in the bowels of the expression generation system).Ģ) To pull off inequality chaining, we hold on to a reference to the first inequality that we see (so we know how to properly construct the chained inequality).ģ) When Chris goes to reconstruct the model, the original component is removed, and garbage collection collects the component, but because the chained Generate_relational_string(buf)įile "/usr/local/lib/python2.7/dist-packages/Pyomo-4.0-py2.7.egg/pyomo/core/base/expr.py ", line 491, in to_stringįile "/usr/local/lib/python2.7/dist-packages/Pyomo-4.0-py2.7.egg/pyomo/core/base/expr.py ", line 771, in to_stringįile "/usr/local/lib/python2.7/dist-packages/Pyomo-4.0-py2.7.egg/pyomo/core/base/component.py ", line 488, in to_stringįile "/usr/local/lib/python2.7/dist-packages/Pyomo-4.0-py2.7.egg/pyomo/core/base/component.py ", line 482, in _str_ return self.cname( True)įile "/usr/local/lib/python2.7/dist-packages/Pyomo-4.0-py2.7.egg/pyomo/core/base/component.py ", line 499, in cnameīase = c.cname(fully_qualified, name_buffer)ġ) Chris is performing a comparison somewhere in his logic between model construction and reconstructing the model that includes model components withoutĬalling value().
