Timing Machine Examples Section 3. There is, to my mind, a major classification of algorithms into three types. The symbol algorithms are algorithms for achieving computational and inferential objectives.
Computer languages implement symbol algorithms.
On the contrary, natural language is used for physical and mental algorithms. An example of physical algorithm is a recipe for preparing a dish in the kitchen. A physical algorithm is an algorithm for accomplishing an objective relating to the material world of macroscopic physical objects in spacetime. Mentally counting the children in a classroom is an instance of the mental algorithm of counting. Many types of meditation involve the repetition or chanting of certain words and phrases.
