Heuristic here simply means a rule of thumb that people can follow when they lack the time and ability to conduct an exhaustive logical and empirical analysis. Heuristics are common reactions to rational ignorance, and since I will argue that slippery slope effects are often caused by rational ignorance, the term “heuristic” will come up a lot.

Examples of Heuristic in a sentence

Heuristic versus systematic information processing and the use of source versus message cues in persuasion.
Heuristic processing can bias systematic processing: effects of source credibility, argument ambiguity, and task importance on attitude judgment.
Heuristic and systematic information processing within and beyond the persuasion context.
A Heuristic Algorithm Here we give a simple heuristic algorithm, denoted by hCSC, to solve the CSC problem faster than nCSC, and return an approximation of the best rotation.
ExtensionFlaw = SendEncrypted; SendKey SendEncrypted = A → B : {Data}K SendKey = A → B : K Figure 3.21: Extension Heuristic Flaw Example In our example, we would heuristically guess that the message which revealed Data to host B would be SendEncrypted, since this is where the token is first seen.

Heuristic in general is defined as a problem-solving approach that utilises a practical process (“best practice”) that is fast and efficient in solving a specific problem and achieving immediate results.
Finally it would discover that it is at the beginning of Heuristic, and that this is the root process, so there is no further discovery necessary.
Furthermore, while minimizing the makespan of the HPC system; authors have validated On-line Heuristic Scheduling Algorithm (OHSA).

More Definitions of Heuristic

Heuristic means applying what we know

Heuristic. , from the Greek “heuriskos,” means “process.” Thus, a heuristic is a structured process, approach, or algorithm, that consists of specific steps:

Heuristic. For most interesting problems there is no exact algorithm with polynomial complexity that finds the optimal solution to this problem. In addition, the cardinality of the search space for these problems is usually very large, which makes the use of exact algorithms unfeasible since the amount of time it would take to find a solution is unacceptable. Due to these two reasons, it is necessary to use approximate or heuristic algorithms that allow obtaining a quality solution in a reasonable time. The best definition of a heuristic method is provided by Zanakis et al: "Simple procedures often based on common sense that are supposed to get a good (not necessarily optimal) solution to difficult problems in a simple and fast way". The heuristic algorithms are usually classified as: o Constructive methods: Procedures that are capable of constructing a solution to a given problem. The way to build the solution depends strongly on the strategy followed. o Search methods: They start from a given feasible solution and from it they try to improve it. The main problem presented by heuristic algorithms is their inability to escape from local optima. To solve this problem, other, more intelligent search algorithms are introduced that avoid being trapped in them as much as possible. These more intelligent search algorithms, called meta- heuristic, are high-level procedures that guide known heuristic algorithms, preventing them from falling into local optima. - Meta-heuristic: To obtain better solutions than traditional heuristics, it is necessary to choice techniques that carry out a better exploration of the solutions space. Metaheuristics are generic procedures for exploring the space of solutions for optimization and search problems. They provide a design line that, adapted in each context, allows generating solution algorithms that, in general, obtain better results than classic heuristics, although incurring in longer execution times (which, in any case, are inferior to those of the exact algorithms). Some examples of application of these algorithms are: o Ant algorithms are agent-based procedures that use randomized construction methods and cooperate with each other by sharing information. o ▇▇▇▇-Search Algorithms are local search methods that accept to make the solutions worse to escape local optima. o Genetic Algorithms are based on keeping a set of solutions diverse enough to cover a large part of the solution space.
