Section 3 (Variations) and Section 5-9 (Other Variants) are ambiguous.

The first section discusses variations in terms of the probability distribution and some of the other sections discuss semantic additions to the problem (adversarial approaches) while others discuss very specific variants (duelling bandits) that have little in common with the core material. We need to define some boundaries and categorizations in this article a bit better than we have. I've started this process a little. — Preceding unsigned comment added by 174.4.66.133 (talk) 19:44, 24 December 2017 (UTC)
