Unlike most treatments of dynamic epistemic logic, we have transitions that ``change the state'' of the underlying system and not just the state of knowledge of the agents. The key novel feature that emerges is the need to have a way of ``inverting transitions'' and distinguishing between transitions that ``really happen'' and transitions that are possible.<\/jats:p><jats:p>Our approach is algebraic, rather than being based on a Kripke-style semantics. The semantics are given in terms of quantales. We introduce a class of quantales with the appropriate inverse operations and use it to model toy robot-navigation problems, which illustrate how an agent learns information by taking actions. We discuss how a sound and complete logic of the algebra may be obtained from the positive fragment of PDL with converse.<\/jats:p>","DOI":"10.29007\/8g5j","type":"proceedings-article","created":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T16:46:53Z","timestamp":1516726013000},"page":"82-67","source":"Crossref","is-referenced-by-count":0,"title":["Towards a Logic for Reasoning About Learning in a Changing World"],"prefix":"10.29007","volume":"7","author":[{"given":"Prakash","family":"Panangaden","sequence":"first","affiliation":[]},{"given":"Mehrnoosh","family":"Sadrzadeh","sequence":"additional","affiliation":[]}],"member":"11545","event":{"name":"LAM'10. 3rd International Workshop on Logics, Agents, and Mobility"},"container-title":["EPiC Series in Computing"],"original-title":[],"deposited":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T16:46:56Z","timestamp":1516726016000},"score":1,"resource":{"primary":{"URL":"https:\/\/easychair.org\/publications\/paper\/sx6F"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[null]]},"references-count":0,"URL":"https:\/\/doi.org\/10.29007\/8g5j","relation":{},"ISSN":["2398-7340"],"issn-type":[{"type":"print","value":"2398-7340"}],"subject":[]}}
