What algorithm means in practice
An algorithm is a set of rules used to process information. In a dive computer, a decompression algorithm uses inputs such as depth and time to produce modelled information. Model output should not be confused with a physical measurement.
An example to think through
A useful study exercise is to make two columns: “measured” and “calculated”. Place depth and modelled exposure in different columns, then ask your instructor how the device uses its inputs. This is a conceptual exercise, not a planning calculation.
A common misunderstanding
A more detailed display does not mean the computer knows every individual risk factor.
Underlying concept: PADI — Dive Computers. The example is an original YouDive study prompt, not a reported dive.
