Access UQLab code & examples from Moustapha et al (2022)

I am new to UQLab and I’ve been trying to run through the problem sets that were defined in the benchmark study by Moustapha et al (2022), but I’m having trouble finding a lot of info in the UQLab documentation. The paper says that the 1.4 release has the code and examples included in the documentation, although I was only able to download v2.0 of UQLab. Can anyone help me find the code and example problems within the documentation? (for further reference, I’ve been able to define almost all of the problems based on the supplemental material from the paper, but I’m still having trouble running the ALR algorithm with problems that have >2 variables and a complicated function.)

Any help would be greatly appreciated!
