Intelligent agents have a wide range of applications in robotics, video games, and computer simulations. However, fully general agents should function with as little human guidance as possible. Specifically, agents should ...

Tetris is a challenging puzzle game that has received much attention from the AI community, but much of this work relies on intelligent high-level features. Recently, agents played the game using low-level features (10 X ...

Let f and g be functions analytic on the unit disk and let I*
denote the Bergman norm. Conditions are identified under which there exists an
absolute constant c, with 0 < c < 1, such that the relationship Ig(z)I < ...

Using a theorem of S. Bernstein [1] we prove a special case of the
following maximum principle for the Bergman space conjectured by B. Koren-
blum [3]: There exists a number S e (0, 1) such that if / and g are ...

Sharp inequalities are established between the Gaussian hypergeometric function and the power
mean. These results extend known inequalities involving the complete elliptic integral and the hyper-
geometric mean.
Richards, Kendall C.(Journal of Inequalities in Pure and Applied Mathematics, 2006)
Recently obtained inequalities [12] between the Gaussian hypergeometric func-
tion and the power mean are applied to establish new sharp inequalities involv-
ing the weighted identric, logartithmic, and power means.
Richards, Kendall C.(Journal of Inequalities in Pure and Applied Mathematics, 2007)
In this note, we present sharp inequalities relating hypergeometric analogues of the
arithmetic-geometric mean discussed in [5] and the power mean. The main result generalizes the
corresponding sharp inequality for the ...

It was recently shown that if M = 1 ⊕ ··· ⊕ k ∈ Cn×n is a
Jordan matrix with k nontrivial Jordan blocks i, then M can be
