Backward Chaining

Backward chaining is a reasoning method used in problem-solving and decision-making. It starts with the desired outcome or goal and works backward to determine the necessary conditions or steps needed to achieve that goal. Essentially, you identify what you want to achieve, then ask, "What must be true for this to happen?" By tracing back through the necessary steps, you can effectively find a logical path to your goal, ensuring that all required prerequisites are met. This approach is often used in artificial intelligence and expert systems to derive conclusions from known facts.
