Detailed explanation-1: -Answer: A heuristic is used when it’s impossible or impractical to use an algorithm to solve a problem. Therefore, we need something that is good enough on average for most instances. This is where a heuristic shines.
Detailed explanation-2: -Heuristic methods can help ease the cognitive load by making it easy to process decisions. These include various basic methods that aren’t rooted in any theory per se but rather rely on past experiences and common sense. Using heuristics one can, therefore, resolve challenging and non-routine problems.
Detailed explanation-3: -In computer science, a heuristic is a problem-solving strategy or method that is not guaranteed to find the optimal solution, but is designed to find a satisfactory solution in a reasonable amount of time.
Detailed explanation-4: -A heuristic function, also simply called a heuristic, is a function that ranks alternatives in search algorithms at each branching step based on available information to decide which branch to follow. For example, it may approximate the exact solution.
Detailed explanation-5: -An algorithm is a step-wise procedure for solving a specific problem in a finite number of steps. The result (output) of an algorithm is predictable and reproducible given the same parameters (input). A heuristic is an educated guess which serves as a guide for subsequent explorations.
