K-line (artificial Intelligence)
A K-line, or Knowledge-line, is a mental agent which represents an association of a group of other mental agents found active when a subject solves a certain problem Problem solving is the process of achieving a goal by overcoming obstacles, a frequent part of most activities. Problems in need of solutions range from simple personal tasks (e.g. how to turn on an appliance) to complex issues in business an ... or formulates a new idea. These were first described in Marvin Minsky's essay K-lines: A Theory of Memory, published in 1980 in the journal ''Cognitive Science'': When you "get an idea," or "solve a problem" ... you create what we shall call a K-line. ... When that K-line is later "activated", it reactivates ... mental agencies, creating a partial mental state "resembling the original." "Whenever you 'get a good idea', solve a problem, or have a memorable experience, you activate a K-line to 'represent' it. A K-line is a wirelike structure that attaches itself to whi ...

Computational Problem
In theoretical computer science, a computational problem is a problem that may be solved by an algorithm. For example, the problem of factoring :"Given a positive integer ''n'', find a nontrivial prime factor of ''n''." is a computational problem. A computational problem can be viewed as a set of ''instances'' or ''cases'' together with a, possibly empty, set of ''solutions'' for every instance/case. For example, in the factoring problem, the instances are the integers ''n'', and solutions are prime numbers ''p'' that are the nontrivial prime factors of ''n''. Computational problems are one of the main objects of study in theoretical computer science. The field of computational complexity theory attempts to determine the amount of resources ( computational complexity) solving a given problem will require and explain why some problems are intractable or undecidable. Computational problems belong to complexity classes that define broadly the resources (e.g. time, space/memory, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
