In Choice Tasks Section (tournament ACBC) are included only concepts shown previously in the Screening Section?

If a concept will not appear in the Screening Section (ex: if there are too many attributes and levels), it will not have the chance to be evaluated in Choice Tasks Section (tournament ACBC)?

I don't understand your comment that a concept would not be shown in the Screening Section due to too many attributes and levels.  Perhaps you can clarify?
I have 11 attributes, each with 3-8 levels. The 1st attribute is Brand with 3 levels, and in the first 8 screening questions one of the brands was never shown, therefore is no chance to by evaluated in the Tournament section. Shall I increase the no of screening questions or reduce the no of levels? Tx
Why does one of the brands never appear across the first 8 screening questions?  The software tries to make sure each level is shown multiple times (even if the brand is not a BYO-selected brand).  Do you have lots of prohibitions?  What about how many attributes you are allowing the software to modify from the BYO selections the respondent makes?  If you have 11 attributes, you should be asking the software to vary from 2 to 4 attributes from the BYO selections to generate the near-neighbor concepts.
I didn't put prohibitions on brands so I expected to see all the brands in the screening questions. Perhaps it is because min 2 and max 4 attributes are allowed to modify from the BYO question? Or, is there any limitation in the ACBC trial version? We just bought a license and now everything goes fine, but the event I'm talking about happened before when I used the trial version to convince the client about it's utility. We currently run a study on telecom and I will let you know about other issues, if any. Thanks
The demo version shouldn't make a difference about the quality of the design.  Sorry, I don't know what has happened in your previous study.

Indeed, only concepts shown (and chosen as "a possibility") in the Screening section are taken forward to the Tournament section of ACBC.
