The experiment lacks randomness.

Hi,

I'm a bit confused about why I'm getting the same results every time I use the experiment. Even when I press the "delete results file" button and then run it again, the results remain identical. This issue has been bothering me for a while, and I greatly appreciate your assistance.

The results are the same every time after resetting.

Can I ask why you need this? I've never found a good reason to use it.

I'm unable to replicate this issue. I ran an experiment with a random value as a performance measure. With the "initialize random streams based on system time" box checked, I could not repeat the results of the experiment at any point.

Please upgrade to the latest bug fix release available. If that does not resolve your issue, you'll need to post your model.
