A heuristic device is used when an entity X exists to enable understanding of, or knowledge concerning, some other entity Y. A good example is a model that, as it is never identical with what it models, is a heuristic device to enable understanding of what it models. Stories, metaphors, etc., can also be termed heuristic in this sense.
Another example of heuristic making an algorithm faster occurs in certain search problems. Initially, the heuristic tries every possibility at each step, like the full-space search algorithm. But it can stop the search at any time if the current possibility is already worse than the best solution already found.
A heuristic evaluation is a usability inspection method for computer software that helps to identify usability problems in the user interface design. It specifically involves evaluators examining the interface and judging its compliance with recognized usability principles (the " heuristics ").
For example, the popular National Semiconductor 16550 has a 16-byte FIFO, and spawned many variants, including the 16C550, 16C650, 16C750, and 16C850. Depending on the manufacturer, different terms are used to identify devices that perform the UART functions. Intel called their 8251 device a "Programmable Communication Interface".
Heuristic routing is used for traffic in the telecommunications networks and transport networks of the world. Heuristic routing is achieved using specific algorithms to determine a better, although not always optimal, path to a destination. When an interruption in a network topology occurs, the software running on the networking electronics can ...
Build well: Take full advantage of these inherent properties, such as fallbacks, flexibility, and user control, to construct universally usable Web sites. Favor HTML over other formats: HTML is the best format for universal usability. Provide documents in nonstandard formats, such as PDF and Flash, only as an alternative to accessible html.
This finish time depends on the communication time to send all necessary inputs to the worker, the computation time of the task on the worker, and the time when that processor becomes available (it may be busy with another task). HEFT uses an insertion-based policy that fills sufficiently sized gaps between already scheduled tasks.
