[SOSlib-devel] Parameter Scan functions in SOSlib

[Rainer M. <ra...@tb...>]

Hi Akira, Eryk and Norihiro,

(CCed also to the SOSlib development list)

you are all using/interested in the high-level SOSlib 
interface SBML_odeSolverBatch for efficient parameter/initial condition 
scans.

Currently, it is implemented with a serious and stupid malfunction - 
i.e. n parameters can be varied over m arbitrary points (design points), 
but there are no combinations of parameter values.

CellDesigner needs results for each combination of parameter values, and 
this is the general requirement for such a batch function.
I want to correct this now.

There are two questions:

1) Do you see a need for n parameters to be varied, and to get a result 
structures for each combination? This would result in a n*n*m*m matrix of 
SBMLResults. Or is it generally sufficient to provide this scan only for 2 
parameters?

2) As we now want to vary over m arbitrary design points, m (the number of 
parameter values to be scanned for one parameter) could be different for 
each parameter. I.e. one parameter might be varied over 3 values, while 
the other parameter might be varied over 16 values.

Implementing 2, i.e. a different m for each parameter would be much easier 
if we restrict the batch function to 2 parameters!

What do you think? Or better asked: what are your requirements?

If you want you can add things to the respective section at

(email ha...@tb... to get an account, mention that you 
want to contribute to SOSlibDevel Wiki).
