Dynamic Gossip is a generalization of the classic telephone problem:\u00a0Suppose you and your friends each know a secret. Whenever you make a\u00a0phone call you tell each other all secrets you know. Moreover, at the\u00a0beginning you might not know all phone numbers but you also learn new\u00a0numbers from others, changing the reachability graph.<\/p>\n<p>Recent work focused on simple protocols like &#8220;Learn New Secrets&#8221; and\u00a0has characterized their success conditions and execution length. These\u00a0protocols sometimes fail because they ignore information available to\u00a0the agents which would allow better coordination.\u00a0Therefore, we study in which ways epistemic protocols for dynamic gossip\u00a0can be strengthened, using epistemic logic as a simple protocol language\u00a0with a new operator for protocol-dependent knowledge.\u00a0This talk will give an introduction to the Dynamic Gossip problem and\u00a0then present some new ideas on epistemic strengthenings of protocols.<\/p>\n<p>Joint work with Hans van Ditmarsch, Louwe B.
