Multiple issues wikify February 2012 refimprove October 2007 context October 2009 In psychology , an effort heuristic is a rule of thumb in which the value of an object is assigned based on the amount of perceived effort that went into producing the object. An example of this would be the comparison of 100 earned, and 100 found. If someone finds 100 they might go spend it on a whim, but if that 100 is part of their paycheck, they are not going to waste it. Another way that effort heuristic can be considered is the amount of effort a person will put into an action depending on the goal. If the goal is of little importance, the amount of effort a person is willing to put into it is going to be lower. The effort heuristic can also affect the perceived quality rating and financial value of objects. Kruger et al. ref cite journal author Justin Kruger, Derrick Wirtz, Leaf Van Boven, and T. William Altermatt year 2004 title The effort heuristic journal Journal of Experimental Social Psychology volume 40 issue 1 pages 91 98 doi 10.1016 S0022 1031 03 00065 9 ref found that people who were told that a poem required 18 hours to write rated it as higher quality and gave it a higher appraised value than did people who were told that it took only 4 hours to write. They found a similar effect in the valuation of paintings. In a third study, the researchers asked students to rate the quality of medieval armor that was shown in pictures and accompanied by a description that included manufacturing time. For the pieces of armor that were shown in clear pictures, there was only a small difference in ratings between those pieces that had long versus short manufacturing times, but when the pictures were blurry, the students gave substantially higher quality ratings to pieces of armor when the manufacturing time was long. Other students gave lower ratings to the same pieces of armor when the description listed only a short manufacturing time. The manipulation of blurry pictures suggested ... more details

In computer science , specifically in algorithm algorithms related to Pathfinding , a heuristic function is said to be admissible if it is no more than the lowest cost path to the goal.

Heuristic is an adjective used in relation to methods of learning, discovery, or problem solving. Routing is the process of selecting paths to specific destinations. blockquote According to Schuster 1974 The heuristic approach to problem solving consists of applying human intelligence, experience, common sense and certain rules of thumb or heuristics to develop an acceptable, but not necessarily an optimum, solution to a problem. Of course, determining what constitutes an acceptable solution is part of the task of deciding which approach to use but broadly defined, an acceptable solution is one that is both reasonably good close to optimum and derived within reasonable effort, time, and cost constraints. Often the effort manpower, computer, and other resources required, the time limits on when the solution is needed, and the cost to compile, process, and analyze all the data required for deterministic ... heuristic approach. Thus, the heuristic approach is generally used when deterministic techniques or are not available, economical, or practical. p.9 blockquote Heuristic Routing is a system used to describe how data is delivered when problems in a network topology arise.
