What is the rule/algorithm to find near-neighbor concepts within ACBC?

Hello everyone,

I am wondering if there is a rule or algorithm that SSI Web respectively Lighthouse Studio 9 is using to find near-neighbor concepts for the screening-task after respondents did the BYO-task?

If so, could someone describe the procedure to me?
Thank you of your support!

The rule first looks at how many attributes it is allowed to change from the BYO task.  It is a random number between Minimum Attributes to Vary from BYO Selections and Maximum Attributes to Vary from BYO Selections. So if the min is 2 and the max is 4 then lets say it randomly chooses 3.  Then it  randomly chooses 3 attributes to modify its levels and changes them including the least changed ones.  The changes are allowed as long as they don't violate prohibitions and alternative specific designs.  If the attributes were not included in the BYO then it will always change that attribute.
