Algorithm
An algorithm is a specified method of effective computation. Its input, output and termination requirements depend on the task; online processing additionally accounts for inputs arriving over time.
Overview
Computability asks whether a procedure can solve every input of a specified task; the general halting problem is undecidable in the Turing-machine model. Complexity asks how resource use grows. Whether NP-complete problems admit deterministic polynomial-time algorithms remains unresolved as part of P versus NP.
Why it matters
Algorithms support tasks as different as sequence searches and screening for care-management programs. In a studied health-care system, predicting spending produced different priorities from assessing illness. Evaluating such a system therefore requires examining its prediction target as well as its accuracy.
