I am experiencing the same problem in my Workshop activity (in Moodle 4.1) as the post Assessment allocation uneven.
When I use the random allocation, for example, on a per-submission basis, the number of reviewers is even, but the number of reviewees is (often) not.
Attached images are my minimum example with four submissions.
I am not using any group mode, and removing existing allocations before new allocation.
This is one of the allocation result.
Hello,
With a smaller number of participants uneven random allocation can happen. You could try changing the number of reviews to per reviewer instead or per submission, or use manual allocation to ensure the number of reviewees is even.
Hi Helen,
Thanks for the reply.
Indeed, it seems that participants are allocated evenly when there are many participants.
Is there a bound on the number of participants where even allocations are guaranteed? Or is the probability of uneven allocations only very small and not zero?
In the latter case, it would take a lot of time to check if the results of random allocations are even, and I would not be able to use scheduled allocations with confidence. It would be very nice if the random allocation algorithm is improved so that even allocations are guaranteed for any number of participants.
