This feedback is used as a part of equals/hashCode, therefore 2 same paths with different result will be recognized as different feedbacks. Is it intented?

You can find similar util method in RandomExtension.kt (in module utbot-fuzzing) with name Random.chooseOne. Also, please not, that random in your case doesn't use seed, therefore, every run will be different, that usually is undesirable.

The random is still no-seed random. Also, you can pass to the chooseOne just weights.toDoubleArray. The method chooseOne does sum itself, so, there's no need to do it before.

I'd recommend extracting the cache into a separate class to facilitate further work with it.
Description
Added socket connection between python and kotlin. Now it works 10 times faster then previous verision.
Fixes #1856
How to test
Manual tests
Generate tests for python function, for example, with many branches.
