KiSAO term 407 is the generic steady state algorithm, so it is likely that the problem is that substituting a more-specific algorithm for the generic one has not been implemented. I could be wrong, and I could also be wrong about what repository the error message came from! But this was my best guess.
Not much has been done with steady state. To start, it would be helpful to get code from Frank Bergmann for use with COPASI. There's minimal bandwidth for now.
When validating biomodels models, I get the following error a lot:
NotImplementedError: Algorithm substitution for "steady state method" (http://www.biomodels.net/kisao/KISAO#KISAO_0000407) for policy SAME_VARIABLES is not supported.
