How to Use
There are two ways to execute this tool.
The main file is irankfinder.py, you can run this command to get all the information:
$ python irankfinder.py --help
The second way is: including the module termination
import termination # config must be a dictionary with all the information needed termination.analyse(algorithms, cfg) # or for non termination termination.analyse_nontermination(algorithms, cfg) # where algorithms is a list of algorithm objects from termination.algorithm
You can also run a concrete algorithm, but it is not recomended.
from termination.algorithm.lrf import PR lrf_pr = PR() lrf_pr.run(cfg)
