I am having trouble using NMinimize in Mathematica 9 - Memory consumption overflows.

The same NMinimize command, with the same function to minimize, in Mathematica 7 and 8, gives acceptable results.

Is this a bug? Anyone else has had similar issues? Any workarounds ?

How are we to know or confirm anything or suggest a workaround if you do not provide an example? Please edit your post to include a minimal example that reproduces the problem, showing the memory increase in 9, but not 7 and 8. – R. M. Oct 23 '13 at 20:41
@rm-rf I can send you the nootebook. The code is very large. If I simplify the code im not sure that i can obtain the same behavior. Do I send you the notebook? – alcohol Oct 23 '13 at 20:49
I'm afraid I won't have the time to look through a very large code base (and am reluctant to, as well). I suspect most folks here might feel the same, which is why we suggest reducing the problem to a minimal example. If that is not possible, it seems to me like your best bet here would be contacting Wolfram support directly at They have resources at their disposal to closely reproduce your system config and check to see if the memory leak can be reproduced as well. BTW, are you running 9.0.0 or 9.0.1? – R. M. Oct 23 '13 at 20:55
