Yes, seems to work now! Okay, lessions learned. Solution code for random test cases will be written into the test cases in future work.
I am used to seperate my code in real projects and misused the preload section for this purpose. Thanks for helping!

As I mentioned at my fork three days ago:
"It seems to me that the old translation is still used (where the preloaded class for the test cases is sill missing).
Could you try do figure out how to get the new fork running?
This translation thing is much more confusing than initially thought ;-)"

The old version is still used. I have no idea how I could change this, so I hope you can choose the version which should be used?! You can try it out by training the PHP version and clicking "run suit" directly. If "Error: Class 'PolynomialSimplifier' not found" is still in the output, the old version is used, because I renamed the class to "PolynomialSimplifierSoltuion" for the Test Cases in the working fork.

Hey, indeed. I forgot to preload a class for the testcases.
There is a new fork of my translation with the correct preload and updated test cases. When I try to edit my original translation I get an error with the message "Description cannot be approved, recent changes from related record must be merged first.". So I hope forking my translation was the correct way of handling this error.

Fixed, cheers!

Hey SleepingCode,

calling me would be great, thank you :-) It was my first kata translation, so I would appreciate every feedback I can get.

I've created a fork with that change. It still shows me syntax error for non-existant symbol, though.

I have probmes with saving and even running the tests for kata, system tells me about syntax error, which doesn't exist...
If you're going to do something with the task, can you please try replacing sublistOf "abcdxyz" with suchThat (sublistOf "abcdxyz") (not . null) in test cases - it should fix the problem.

Hey, I've found an issue and fixed it, but now I cannot update it due to changes in description:
"Description cannot be approved, recent changes from related record must be merged first."

I apologize for being so lazy to solve something so easy. Thanks for your observation and your polite help. It's solved.

Still the same error. I asked for feedback but got no response. I reject this translation. Maybe you could recreate it from the current kata version?

Hey! I work for a company where we actually have to code this sort of stuff, so I was making up some problems to give to people applying for jobs :)
I tend to use numpy because I think providing the numpy library is a good hint and its documentation is a nice list of things you could do (plus my machine learning + Matlab background), but I totally agree that it can be done other ways.
