... addition to learn- ing game strategies guided by the selected text. Our method operates in the Monte-Carlo search framework, and learns both text anal- ysis and game strategies based only on envi- ronment ... horizons, and high-branching factors, this approach can be prohibitively slow and ineffective. An algorithm with access to the text, however, could learn correlations between...
