![]() ![]() The command to solve a (generalized) parity game using SPORE is: The usage instructions for the standalone SPORE (generalized) parity game solver can be accessed using python spore.py -h. configure -enable-max-accsets=64 to allow the generation of some additional automata. If needed, the user can increase the number of acceptance sets used by Spot using the following option. Instructions on how to compile Spot can be found on Spot's website. The full BDD approach also requires Spot, more precisely the ltl2tgba command.Instructions on how to install are provided in its repository. Note that dd should be compiled with CUDD support. Dependencies can be found in requirements.txt. SPORE is written using Python 2.7 and should be fully Python 3 compatible.Instructions on how to use and build tlsf2gpg can be found on tlsf2gpg's repository.In the regular version, the generalized parity game was created explicitly before being translated into a BDD representation. The improvement in this updated version, which we call the "full BDD" approach, is therefore to allow for an earlier introduction of BDDs in the LTL to generalized parity game translation, leading to a smaller symbolic representation of this game. Game, and the same algorithms introduced in the regular version of SPORE are used to solve the generalized parity game and decide whether the input formula is realizable. It is afterwards translated into a symbolic generalized parity Leading to a single generalized parity automata. SPORE translates those automata into symbolic parity automata, then computes the product of those automata,.These automata are stored in a temporary automata/game/ folder in the Hanoi Omega-Automata (HOA) format. Every LTL formula is then sent to ltl2tgba,Ī command from Spot, which generates a corresponding deterministic parity automaton.The script scripts/create_parity_automata.sh extracts the input and output atomic propositions from the LTL formula in TLSF format and splits it into sub-formulas using SyfCo.In order to optimize the practical execution time of SPORE's LTL realizability toolchain, the following updated operations have been introduced to obtain the generalized parity game. SPORE implements both explicit and symbolic (BDD-based) algorithms to solve (generalized) parity games and decide whether the input formula is realizable.Ī description of the partial solvers implemented in SPORE and references to the recursive algorithm for (generalized) parity.This translation from LTL to generalized parity games is done using a modified version of tlsf2gpg. Input LTL formulas in TLSF format are split into sub-formulas which are used to generate a generalized parity game.Toolchain used by SPORE is the following: SPORE is a prototype tool meant to test the feasibility of using generalized parity games in the context of LTL realizability. ![]() The LTL realizability toolchain of SPORE uses code from either tlsf2gpg, or Clément Tamines, University of Mons ( website).Gaëtan Staquet, University of Mons ( website).Christophe Grandmont, University of Mons.Charly Delfosse, University of Mons ( website).Whatever the case may be, one thing’s for sure: video games bring everyone together.SPORE: Symbolic Partial sOlvers for REalizabilityĪ prototype symbolic implementation of partial solvers for (generalized) parity games applied to LTL realizability.
