1. I fixed the merge issue and also remerged to capture more recent changes.
2. I did as you suggested and introduced a local variable to hold a value
used in the closure. *Unfortunately, the test still fails. Since all values
used in the closure are local variables, I do not know what to do at this
point.*
3. The best fix to the problem with the test that selects two random
centers is the one that I implemented. It will pass the test
deterministically, while still using any random seed.
