Título: Planning under Risk and Knightian Uncertainty

Palestrante:  Leliane Nunes de Barros

Resumo: 
Two noteworthymodels of planning in AI are probabilistic planning (based
on MDPs and its generalizations) and nondeterministic planning (mainly
based on model checking). In this paper we: (1) show that probabilistic
and nondeterministic planning are extremes of a rich continuum of
problems that deal simultaneously with risk and (Knightian) uncertainty;
(2) obtain a unifying model for these problems using imprecise MDPs; and
(3) derive a simplified BellmanÇs principle of optimality for our mode.
