Various methods based on existing algorithms or on existing sufficient conditions are developed. The methods are tested on a large variety of random systems and the results are visualized. The two strongest sufficient conditions are proved to be equivalent under a certain assumption. The topic of detecting solvability is also touched upon.Keyphrases: full column rank, interval linear systems, unsolvability, unsolvability gap In: Matthieu Martel, Nasrine Damouche and Julien Alexandre Dit Sandretto (editors).
