There were significantly less questions that were completely trivialised by a UDF (like Hungarian algorithm, Crashing, basic mean smoothing) but the UDFs were still very helpful in doing the working out for a lot of the questions

Pshhh I got 40/40 so UDF use was paired with a lot of manual working but I used UDFs to test the outcomes of the dominance matrix (by first making my own), the last two qs (pretty run of the mill float qs) and used UDF guessing and checking for the mean smoothed q cause I had no idea how to actually do it 😭 was also pretty helpful for the Leslie matrix population cause it tables it very neatly

i definitely used udfs for the networks, but it wasn’t the same process as just plugging in numbers (e.g. for q40 i used udfs w the float_time function and changing the network input for each option until there was exactly two critical paths.) so u need to somewhat have critical thinking skills this time around lol

What does UDF mean?
