Choosing Well Your Opponents: How to Guide the Synthesis of Programmatic Strategies

IJCAI 2023poster

This paper introduces Local Learner (2L), an algorithm for providing a set of reference strategies to guide the search for programmatic strategies in two-player zero-sum games. Previous learning algorithms, such as Iterated Best Response (IBR), Fictitious Play (FP), and Double-Oracle (DO), can be co…

Show Me the Way! Bilevel Search for Synthesizing Programmatic Strategies

AAAI 2023technical

The synthesis of programmatic strategies requires one to search in large non-differentiable spaces of computer programs. Current search algorithms use self-play approaches to guide this search. The issue with these approaches is that the guiding function often provides a weak search signal. This is…

What Can We Learn Even from the Weakest? Learning Sketches for Programmatic Strategies

AAAI 2022technical

In this paper we show that behavioral cloning can be used to learn effective sketches of programmatic strategies. We show that even the sketches learned by cloning the behavior of weak players can help the synthesis of programmatic strategies. This is because even weak players can provide helpful in…
