Which of the following is NOT a characteristic of an algorithm?

Choose the correct answer:

Explanation

Correct Option: (c) Scalable

Solution

Standard Characteristics of an Algorithm

According to Donald Knuth and foundational computer science principles, a sequence of instructions must satisfy several specific criteria to formally qualify as an algorithm.

Let an algorithm be represented as a transformational system $A$ mapping an input space to an output space. It must strictly adhere to the following properties:

Input: An algorithm must have zero or more well-defined inputs ( $I \geq 0$ ) taken from a specified set of quantities.
Output: It must yield at least one well-defined output quantity ( $O \geq 1$ ) that possesses a clear relationship to the initial inputs.
Definiteness (Unambiguousness): Each step of the algorithm must be clear, precise, and completely unambiguous. There should be exactly one interpretation of what needs to be executed.
Finiteness: The algorithm must terminate after a finite number of execution steps ( $N < \infty$ ). It cannot run into an infinite loop during processing.
Effectiveness (Feasibility): Every instruction must be basic enough to be carried out using pencil and paper in a finite amount of time.

Analysis of the Options

Option	Characteristic	Status	Explanation
(a)	Input	Valid	Essential for initializing state variables and supplying datasets to the logic.
(b)	Output	Valid	Essential for returning computed solutions, flags, or transformations.
(c)	Scalable	Invalid	Scalability is a desirable system architectural or performance design goal, but it is not a defining structural characteristic required for a sequence to be an algorithm. A poorly scaling algorithm is still an algorithm.
(d)	Definiteness	Valid	Guarantees that the instructions are mathematically precise and executable without ambiguity.

Therefore, Scalable is not counted among the foundational core attributes of an algorithm, making (c) the correct option.
