As an effective method , an algorithm can be expressed within a finite amount of space and time,  and in a well-defined formal language  for calculating a function. The transition from one state to the next is not necessarily deterministic ; some algorithms, known as randomized algorithms , incorporate random input. The concept of algorithm has existed since antiquity. Arithmetic algorithms, such as a division algorithm , was used by ancient Babylonian mathematicians c. Later formalizations were framed as attempts to define " effective calculability "  or "effective method".
