Center node: "best effort strategies for losing states"
  Abstract: We consider games played on finite graphs, whose goal is to obtain a trace belonging to a given set of winning traces. We focus on those states from which Player 1 cannot force a win. We explore and compare several criteria for establishing what is the preferable behavior of Player 1 from those states. #R##N#Along the way, we prove several results of theoretical and practical interest, such as a characterization of admissible strategies, which also provides a simple algorithm for computing such strategies for various common goals, and the equivalence between the existence of positional winning strategies and the existence of positional subgame perfect strategies.

Connected through hyperedge HE-1 (induced by source paper "synthesizing least limiting guidelines for safety of semi autonomous systems"):
  with members:
    - "maximally permissive controlled system synthesis for modal logic"
    - "counter strategy guided refinement of gr 1 temporal logic specifications"
    - "environment assumptions for synthesis"
