Defining "Ill-defined" problems
Problem or domain is ill-defined when
essential concepts, relations, or features of it are un- or under-
specified or intractable requiring a solver to frame or
recharacterize the problem or the concepts as part of the
solution process.
Since ill-defined domains lack a single strong domain theory
uniquely specifying the essential concepts, relationships, and
procedures for the domain and providing a means to validate
problem solutions, a solver is required to structure or
recharacterize the domain when working in it.
