    A simple reasoning engine that solves a limited set of problems.
    
    This class provides a basic framework for solving problems using logical rules.
    It is designed to be extensible but currently handles only specific cases.

    Attributes:
        knowledge_base (dict): Stores the current state and knowledge.
        problem_solvers (list): List of functions that define how to solve different types of problems.
    
    Methods:
        add_knowledge: Add new information to the knowledge base.
        register_problem_solver: Register a function as a problem solver for specific conditions.
        run_inference: Run inference based on current knowledge and registered solvers.
