Abstract

This paper provides a general overview of EqArgSolver, a solver for enumeration and decision problems in argumentation theory. The solver is implemented from the ground up as a self-contained application in C++ without the use of any other external solver (e.g., SAT, ASP, CSP) or libraries.

Notes

  1. 1.

    Henceforth, these assignments will be referred to as legal assignments.

  2. 2.

    Some filtering to eliminate solutions not leading to maximal extensions in preferred/stable semantics problems is also done, although this is not shown in Algorithm 1. For full details, refer to [7].

  3. 3.

    The version of EqArgSolver submitted to the 2nd ICCMA did not take advantage of this simple optimisation, but since submission it has been incorporated offering a huge performance improvement in certain classes of large graphs.
