Backward chaining is a problem-solving method that is widely used in artificial intelligence and computer science to achieve a particular goal. However, there are other synonyms for the term that also indicate the same concept. One of the synonyms is 'backward reasoning' which means the same logical thinking steps are taken in reverse, starting at the end goal and working to the initial step. Another synonym is 'goal-driven reasoning' which means to find a solution by focusing on the final goal and working backward to find the necessary steps required to achieve it. 'Inferential reasoning' is also a synonymous term used to refer to logical reasoning that involves assumptions based on observations and experiences.
