The Data Mining Forum (v2)

where can I find the free code for high utility itemset mining?

In the SPMF library there are open source algorithms for the high utility itemset mining. You can check It. It is quite extensive

I saw the list is indeed quite long for high utility itemset mining in SPMF. That must have taken a lot of time to implement all those algorithms.

Yes, you can check the SPMF data mining library. It offers the code of numerous algorithms for high utility pattern mining tasks such as high utility itemset mining, high utility sequential pattern mining and high utility sequential rule mining.
