Algorithm vs. Heuristic: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
An algorithm is a set of defined, systematic steps for solving a problem, while a heuristic is a general problem-solving approach, often based on experience or intuition.
Key Differences
An algorithm is a detailed, step-by-step procedure designed to solve a specific problem or perform a specific task. It is precise and unambiguous, ensuring consistent results every time it is applied. On the contrary, a heuristic is a more general problem-solving technique, often relying on experience, educated guesses, or intuitive judgment. It is less structured than an algorithm and does not guarantee a correct or optimal solution.

Algorithms are often used in mathematics and computer science for tasks such as data processing and automated reasoning. Their clear and specific instructions make them reliable and predictable. Heuristics, however, are commonly used in situations where a quick, satisfactory solution is more valuable than a precise one. They are particularly useful in complex situations where an exhaustive search is impractical or impossible.

The development of an algorithm involves a thorough understanding of the problem's structure, leading to a series of logical steps to reach the solution. In contrast, the creation of a heuristic is usually based on trial and error, expert knowledge, or practical experience. Heuristics are more flexible and adaptable but might lead to different outcomes when applied by different people or in different contexts.

In terms of efficiency, algorithms are usually more time-consuming to develop but are efficient in execution, especially for well-defined problems. Heuristics, while quicker to implement, may lead to less efficient problem-solving, as they may not always follow the most direct path to the solution.

Lastly, while algorithms are ideal for problems with a clear set of rules and known outcomes, heuristics are more suited for complex, real-world problems where speed and practicality are crucial, and the variables are too numerous for a defined algorithmic approach.
