Advances in Applied Mathematics.
In the known non-stationary case, the authors in 48 produce an alternative solution, a variant of UCB named Adjusted Upper Confidence Bound (A-UCB) which assumes a stochastic model and provide upper-bounds of the regret.

They also provide a regret analysis within a standard linear stochastic noise setting.
