## al·go·rithm

(al'gō-ridhm),
A systematic process consisting of an ordered sequence of steps, each step depending on the outcome of the previous one. In clinical medicine, a step-by-step protocol for management of a health care problem; in computed tomography, the formulas used to calculate the final image from the transmitted x-ray data.

## algorithm

Decision-making A logical set of rules for solving a specific problem, which assumes that all of the data is objective, that there are a finite number of solutions to the problem, and that there are logical steps that must be performed to arrive at each of those solutions NIHspeak A step-by-step procedure for solving a problem; a formula.

## algorithm,

n an explicit protocol with well-defined rules to be followed in solving a complex problem.

## algorithm

a set of rules designed to solve a specific problem by proceeding through a series of prearranged, logical steps. Originally referred to purely mathematical problems, now used in a wider sphere, e.g. to solve diagnostic problems. Often depicted in the form of a box and line diagram which sets out the logic of the procedure or program.

diagnostic algorithm
mapping of the logical steps to be taken in eliminating potential diagnoses which do not match clinical signs or pathological findings and arranging possible diagnoses in order of probability.
