Re: [Swarm-Support] Model actualization (II)

[Paul Johnson]

I think there is probably some slippage between the GUI and your GA 
class and the Parameter object.  My first thought was that the GA code 
itself was not taking the steps necessary to check with the arguments 
object to find out the newest values of the parameters.  I'd put some 
fprintf(stderr,"") diagnostics in to see if the arguments class really 
does have the value from the GUI and then that the GA asks for the 
newest values.

However, you say it works for integers, but not doubles, and that 
perplexes me. You say there are ints and doubles side-by-side in a 
particular object and gui changes in an int work, but gui changes in a 
float do not?  That's a neat trick.  Is it possible you mistakenly used 
"getInt" instead of "getDouble" to retrieve values from arguments?  That 
might break floating point values.

I have no other guesses.

If you send your code in a tarball to me directly, including a README 
problem explaining the trouble, I might spot it pretty easily. If it is 
a hard one to fix and takes me more than a couple of hours, I'm going to 
ask  you for a t-shirt from your university/institute. That's the 
standard fee these days. I'm accumulating some really neat t-shirts from 
various schools around the world.
