**2.**a logical progression that is programmed for a computer.

**3.**a model for making decisions.

## 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.

/al·go·rithm/ (al´go-rith'm)**1.**a step-by-step method of solving a problem or making decisions, as in making a diagnosis.

**2.**an established mechanical procedure for solving certain mathematical problems.

## algorithm

[al′gərith′əm]

**1**a step-by-step procedure for the solution to a problem by a computer, using specific mathematical or logical operations. Compare heuristic.

**2**an explicit protocol with well-defined rules to be followed in solving a health care problem.

## algorithm

(1) A sequential procedure for solving a mathematical problem.(2) A step-by-step procedure for reaching a decision when choosing among multiple alternative options, linked to each other by a decision tree.

## 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.

[Mediev. L.

*algorismus*, after Muhammad ibn-Musa*al-Khwarizmi*, Persian mathematician, + G.*arithmos*, number]## 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.
