Query: An Improved Parametrization and Analysis of the EXP3++ Algorithm for
  Stochastic and Adversarial Bandits   We present a new strategy for gap estimation in randomized algorithms for
multiarmed bandits and combine it with the EXP3++ algorithm of Seldin and
Slivkins (2014). In the stochastic regime the strategy reduces dependence of
regret on a time horizon from $(\ln t)^3$ to $(\ln t)^2$ and eliminates an
additive factor of order $\Delta e^{1/\Delta^2}$, where $\Delta$ is the minimal
gap of a problem instance. In the adversarial regime regret guarantee remains
unchanged.
