==== Conformant planning ====
Conformant planning is when the agent is uncertain about the state of the system, and it cannot make any observations. The agent then has beliefs about the real world, but cannot verify them with sensing actions, for instance. These problems are solved by techniques similar to those of classical planning,<ref>{{Cite journal|title=Compiling uncertainty away in conformant planning problems with bounded width|journal=Journal of Artificial Intelligence Research|last1=Palacios|first1=Hector|volume=35|pages=623–675|last2=Geffner|first2=Hector|year=2009|url=https://www.jair.org/index.php/jair/article/download/10618/25394|doi=10.1613/jair.2708|doi-access=free|access-date=2019-08-16|archive-date=2020-04-27|archive-url=https://web.archive.org/web/20200427045035/https://www.jair.org/index.php/jair/article/download/10618/25394|url-status=live}}</ref><ref>{{Cite conference|title=Effective heuristics and belief tracking for planning with incomplete information|conference=Twenty-First International Conference on Automated Planning and Scheduling (ICAPS)|last1=Albore|first1=Alexandre|last2=Ramírez|first2=Miquel|year=2011|last3=Geffner|first3=Hector|url=https://www.aaai.org/ocs/index.php/ICAPS/ICAPS11/paper/viewFile/2709/3129|access-date=2019-08-16|archive-date=2017-07-06|archive-url=https://web.archive.org/web/20170706012917/https://aaai.org/ocs/index.php/ICAPS/ICAPS11/paper/viewFile/2709/3129/|url-status=live}}</ref> but where the state space is exponential in the size of the problem, because of the uncertainty about the current state. A solution for a conformant planning problem is a sequence of actions. Haslum and Jonsson have demonstrated that the problem of conformant planning is [[EXPSPACE]]-complete,<ref>{{cite
