Did you install the R tool? (RInstaller.exe) The predictive tools and prescriptive tools like Optimization tool are needed for it.
perfect! now let's do some kNN to order the listed songs next!
This was a neat challenge, thank you, @AkimasaKajitani!
It was my first time using the Optimize tool. Depending on how you structure your data, the Optimize output varies.
I used 'Unique' tool to exclude duplicates of song names/energy and duration and the output was very close to the answer provided. When I slightly updated 'Unique' tool to exclude duplicates of song name only regardless of energy and duration, the output was slightly different. I found out the song names were the same in some instances, but energy and duration different - not sure if this was intended :)
Here is my solution attached + spoiler:
My workflow:
My output playlist: slightly different
Total Popularity/Objective: same as solution provided
Playlist duration: a few decimals off - very close :)
Same as the other, I am having different results than others, because one same song, can have multiples Songs ID, Popularity Number and Energy number.
My results here:
My assumptions for this challenge were:
Very tough challenge. It took me a lot of attempts to be able to get the inputs and configuration for the Optimization tool right, but now I'll be ready for the next time I encounter it!
