Issues in Contingency Planning

Cassandra is a partial order planner directly descended from UCPOP, which is sound, complete, and systematic---all plans produced by UCPOP are guaranteed to achieve their goals, if there is a plan then UCPOP will find it, and UCPOP never revisits a partial plan. In this section we discuss these properties and related issues in the context of contingency planning.
