Thank you very much for your work, this is the only relevant package I found, and helps me a lot. I hope you could give me some guidance on my work. 1.in the function mst(item_pool...), how to input the item_pool with a question corresponding to multiple knowledges. 2.I set the number of questions to 900, but I found that it ran very slowly and even reported errors. I would like to ask if there is any range for the setting. Looking forward to your reply.

I need some clarification of your questions.

  1. Can you give me an example of what you mean by one question corresponding to multiple knowledge domains? If you mean one item falls into multiple knowledge domains, then you can add multiple constraints like x <- mst_constraint(x, "content", 10, 10, level=1).
  2. What do you mean by the number of questions, the size of the item pool or the test length? When the problem is too big, it would definitely take a long time to solve. But, there might be a way to cleverly reduce the problem size.
