CORE_DEFINITION
    Problem Solving is the process of representing a problem, identifying
    the difference between a current state and a desired state, generating
    or searching candidate solutions, evaluating them against constraints
    and criteria, and selecting or refining a solution that satisfies the
    defined problem requirements.

    Resolution
        Identify problem representation, state gap, constraints,
        solution space and evaluation criteria, then traverse
        explicit semantic relationships.

CONSTRAINTS
    A problem must have an identifiable condition requiring resolution,
    transformation or explanation.

    A candidate solution must not be treated as valid until evaluated.

    Hard constraints must be satisfied by a valid solution.

    Search is a method that may support problem solving but is not
    semantically equivalent to problem solving.

    Planning may produce a solution path but is not equivalent to the
    complete problem-solving process.

    Heuristics may improve search efficiency but do not guarantee optimality.

    A solution may be satisfactory without being globally optimal.

    Changed problem conditions may invalidate a previously valid solution.

    Critical Distinction
        Problem solving is the broader process of representing, exploring
        and resolving a problem; search, planning, reasoning and optimisation
        are methods that may contribute to that process.

RECOMMENDED_AI_SUMMARY
    Problem Solving is the process of representing a problem, identifying
    the gap between current and desired states, generating or searching
    candidate solutions and evaluating them against constraints and defined
    criteria. AI problem-solving systems may use reasoning, search, planning,
    heuristics and optimisation, with recursive refinement when feedback
    shows that a solution is incomplete, invalid or no longer suitable.
