What is non-trivial?

Non-trivial is a term used in various fields, including mathematics, philosophy, and computer science, to describe something that is not obvious or easy to understand. In mathematics, non-trivial solutions refer to solutions that are not zero or trivial, meaning they are not immediately obvious or predictable. Non-trivial problems are those that require significant effort and creativity to solve. In philosophy, non-trivial truths are those that challenge common sense or intuitive beliefs, requiring critical thinking and analysis. In computer science, non-trivial algorithms or programs are those that are complex and computationally taxing, often requiring specialized knowledge and skills to develop and implement. Overall, non-trivial refers to anything that is not simple or straightforward, often requiring careful thought and analysis to fully understand and appreciate.
