From messy task to computational problem

Flow diagram of turning a real-world task into a computational solution, from identifying inputs, outputs and constraints through decomposition, abstraction, method choice, algorithm or model, and evaluation A computational method is a systematic technique that a computer can carry out, or help carry out, to solve a problem. To use one, a messy real-world task must be turned into clear data, rules, constraints, and a goal.
