In Search of a Compositional Theory of Self-Stabilization

https://blogger.googleusercontent.com/img/a/AVvXsEgUV8paJsfBDCdaizCxyZLf_tgGZc_L1c6HYhST-bupV3snzItwcj-3TzIJnc20dDeTmoFeMaEHxyZpxrqsgI80le-78m0BN7QqcMGPBkhwTLTu-BaWTc0DQ9rpXsag-tonr1n-TYZXz2sRYCk7HQaB94VGFboZ8sPvIL9_mIPGhBpOqL3B_42ueVNyq9o=w393-h400
The author is working on composing self-stabilizing systems using the rely-guarantee approach, inspired by a 2017 control theory paper. They have developed a parametrized model of their retry storm system and applied the small gain theorem to analyze stability. However, they found that the memoryless view of components used in the paper limits its applicability to their example.
