“…Implementation, availability. AbsSynthe is written mostly in Python, and depends only on a simple AIG library (fetched from the AIGER toolbox 22 ) and the BDD package CUDD 23 . The source code is available at https://github.com/gaperez64/AbsSynthe.…”

“…A number of synthesis tools have been developed specifically for the competition (AbsSynthe, Basil, Realizer), while others are new versions or modifications of existing tools (Demiurge, Simple BDD Solver). Recently, the competition format has also been adopted by tool developers that have thus far not participated in SYNTCOMP [22]. Furthermore, the competition has sparked a lively discussion on the implementation of efficient synthesis techniques, in particular making tool developers aware of the range of optimizations used in BDD-based synthesis algorithms, and alternative SAT-and QBF-based approaches that are competitive at least on some classes of benchmarks.…”

Abstract. We introduce the reactive synthesis competition (SYNTCOMP), a long-term effort intended to stimulate and guide advances in the design and application of synthesis procedures for reactive systems. The first iteration of SYNTCOMP is based on the controller synthesis problem for finite-state systems and safety specifications. We provide an overview of this problem and existing approaches to solve it, and report on the design and results of the first SYNTCOMP. This includes the definition of the benchmark format, the collection of benchmarks, the rules of the competition, and the five synthesis tools that participated. We present and analyze the results of the competition and draw conclusions on the state of the art. Finally, we give an outlook on future directions of SYNTCOMP.

“…Chiang and Jiang [85] present a similar approach, which is also inspired by IC3 [24]. While Morgenstern et al [74] solve the game from the perspective of the environment taking the unsafe states as anchor, the approach by Chiang and Jiang [85] takes the perspective of the controller to be synthesized. It uses the initial states as anchor and tries to avoid ending up in an unsafe state.…”

Existing approaches to synthesize reactive systems from declarative specifications mostly rely on Binary Decision Diagrams (BDDs), inheriting their scalability issues. We present novel algorithms for safety specifications that use decision procedures for propositional formulas (SAT solvers), Quantified Boolean Formulas (QBF solvers), or Effectively Propositional Logic (EPR). Our algorithms are based on query learning, templates, reduction to EPR, QBF certification, and interpolation. A parallelization combines multiple algorithms. Our optimizations expand quantifiers and utilize unreachable states and variable independencies. Our approach outperforms a simple BDD-based tool and is competitive with a highly optimized one. It won two medals in the SyntComp competition.

“…As a part of the SYNTCOMP effort, we maintain a public benchmark library 1 which now consists of several thousand benchmark instances from a wide range of domains, and is steadily growing. Moreover, SYNTCOMP has triggered an increased interest in the development of efficient synthesis tools and specification languages that relate to the competition, as witnessed by a growing number of publications on these topics [7,[10][11][12]39] 2 , including tools and research groups that have not participated in the competition thus far [19,22,41,46,56]. SYNTCOMP 2016 introduces a major extension of the competition by dropping the restriction to low-level safety properties.…”

We report on the design of the third reactive synthesis competition (SYNTCOMP 2016), including a major extension of the competition to specifications in full linear temporal logic. We give a brief overview of the synthesis problem as considered in SYNTCOMP, and present the rules of the competition in 2016, as well as the ideas behind our design choices. Furthermore, we evaluate the recent changes to the competition based on the experiences with SYNTCOMP 2016. Finally, we give an outlook on further changes and extensions of the competition that are planned for the future.Comment: In Proceedings SYNT 2016, arXiv:1611.0717
