For example, an artist creates a painting intuitively, based on his or her ideas and emotions, while a computer programmer follows a set of rules and procedures to create a software program. Other antonyms for algorithmic include irregular, unpredictable, and spontaneous. These words describe situations that cannot be easily predicted or controlled by a set of pre-defined rules or procedures.
