# Strix: Explicit Reactive Synthesis Strikes Back!

Authors:
1. [[Phillipp Meyer]]
2. [[Salomon Sickert]]
3. [[Michael Luttenberger]]

## First Pass
**Category:** Design paper. They made a new LTL synthesizer

**Context:** 
Strix is a response to other reative LTL syntehsizer
competition entries.

**Correctness:** 
Seems good to me! They have data to back up their stuff.

**Contributions:** 
They contribute Strix, a tool that uses Determinstic Parity
Automata (DPA) to simplify synthesis. DPA helps Strix solve
problems faster by using parity game solvers as opposed to
symbolic or bounded methods currently used.

**Clarity:** 
Easy to read!

## Second Pass
**What is the main thrust?**
The main thrust is their new tool, Strix.

**What is the supporting evidence?**
They make a testing suite that is supposed to be similar to
the SYNTCOMP2017 testing setup, and run their solver
through the same trials that the competition included. They
achieve pretty good results: much much faster solve times
while also keeping automata size small.

**What are the key findings?**
Strix is pretty good. The use of DBAs seems effective. Their
'quality', a measure of automata size vs specification size,
is also pretty good compared to other synthesizers.

## Third Pass
**Recreation Notes:**

**Hidden Findings:**

**Weak Points? Strong Points?**
