  bibo_abstract:
  - Boolean notions of correctness are formalized by preorders on systems. Quantitative
    measures of correctness can be formalized by real-valued distance functions between
    systems, where the distance between implementation and specification provides
    a measure of “fit” or “desirability.” We extend the simulation preorder to the
    quantitative setting, by making each player of a simulation game pay a certain
    price for her choices. We use the resulting games with quantitative objectives
    to define three different simulation distances. The correctness distance measures
    how much the specification must be changed in order to be satisfied by the implementation.
    The coverage distance measures how much the implementation restricts the degrees
    of freedom offered by the specification. The robustness distance measures how
    much a system can deviate from the implementation description without violating
    the specification. We consider these distances for safety as well as liveness
    specifications. The distances can be computed in polynomial time for safety specifications,
    and for liveness specifications given by weak fairness constraints. We show that
    the distance functions satisfy the triangle inequality, that the distance between
    two systems does not increase under parallel composition with a third system,
    and that the distance between two systems can be bounded from above and below
    by distances between abstractions of the two systems. These properties suggest
    that our simulation distances provide an appropriate basis for a quantitative
    theory of discrete systems. We also demonstrate how the robustness distance can
    be used to measure how many transmission errors are tolerated by error correcting
    codes.@eng
