kandi X-RAY | hylaa Summary

hylaa is a Python library typically used in Manufacturing, Utilities, Automotive, Simulation applications. hylaa has no bugs, it has no vulnerabilities, it has build file available, it has a Strong Copyleft License and it has low support. You can install using 'pip install hylaa' or download it from GitHub, PyPI.

Hylaa (HYbrid Linear Automata Analyzer) is a verification tool for system models with linear ODEs, time-varying inputs, and possibly hybrid dynamics. The is version 2 of Hylaa, with support for resets and hybrid automata with time-varying inputs. The focus has shifted from performance to handling more general dynamics. The latest version of Hylaa is always available on our github repository at . A website for Hylaa is maintained at . The main citation to use for Hylaa is: "HyLAA: A Tool for Computing Simulation-Equivalent Reachability for Linear Systems", S. Bak, P. Duggirala, 20th International Conference on Hybrid Systems: Computation and Control (HSCC 2017). The code was mostly written by Stanley Bak (with input from Parasara Sridhar Duggirala (Hylaa is released under the GPL v3 license (see the LICENSE file). Earlier versions have been approved for public release (DISTRIBUTION A: Approved for public release; distribution unlimited #88ABW-2016-5976, 22 NOV 2016).

You have a label, you are not setting the header correctly. Should be ("header", "value")

You need to call your action from the Component. For this you need to bind it to props first. For this make use of mapDispachToProps component

Install hylaa

This version of Hylaa runs in python3 and requires a few other libraries that you can install with pip3, the python package manager. You must also set your PYTHONPATH environment variable so that it knows where the hylaa source is located. There is a Dockerfile in this repository which is used as part of our continuous integration framework that has step by step commands for installing the necessary packages and dependencies. This serves as the installation documentation, as it's always up to date.
The easiest way to get started with Hylaa is to run some of the examples. Once installed and setup, Hylaa models are just python source files you directly with python3 in a terminal. Go to examples/harmonic_oscillator and run ha.py from the command line (python ha.py). This should create plot.png in the same folder, which will be an 2-d plot of the reachable set. The dynamics in this example are given as x' = Ax, where A is the (potentially sparse) dynamics matrix. This is defined in the define_ha function in the ha.py source file. Initial states and unsafe states are given as conjunctions of linear constraints. These are defined in the make_init function. Finally, computation settings are given in the define_settings function. There are lots of settings that can be adjusted, which can be found in hylaa/settings.py, including comments describing what each one does. The easiest way to use Hylaa on your example is to copy an example from the examples folder and edit that. Notice that models are python code, which means you can create the model programatically using loops or by loading the dynamics from a .mat file.
