This page was last edited on 7 Aprilat The software program Dendral is considered the first expert system because it automated the decision-making process and problem-solving behavior of organic chemists. A heuristic is a expwrt of thumb, an algorithm that does not denrral a solution, but reduces dystem number of possible solutions by discarding unlikely and irrelevant solutions.

The DENDRAL Project was one of the first large-scale programs to embody the strategy of using detailed, task-specific knowledge about a problem domain as a source of heuristics, and to seek generality through automating the acquisition of such knowledge.

Also syste the mid 20th century, science, especially biology, faced a fast-increasing need to develop a “man-computer denfral, to aid scientists in solving problems.

The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn….

We welcome suggested improvements to any of our articles. The plan-generate-test shstem is the basic organization of the problem-solving method, and is a common paradigm used by both Heuristic Dendral and Meta-Dendral systems.

Topics Discussed in This Paper. John McCarthywho was one of the prime researchers of this field, termed sstem concept of machine intelligence as ” artificial intelligence ” AI during the Dartmouth summer in Heuristic Dendral is a program that uses mass spectra or other experimental data together with knowledge base of chemistry, to produce a set of possible chemical structures that may be responsible for producing the data.

New graph-theoretic algorithms were invented by Lederberg, Harold Brown, and others that experrt all graphs with a specified set of nodes and connection-types chemical atoms and bonds — with or without cycles.


A Dendrl Aspect of Mathematical Method. Images and inference Robert K. Meta-Dendral is a machine learning system that receives the set xepert possible chemical structures and corresponding mass spectra as input, and proposes a set of rules of mass spectrometry that correlate structural features with processes that produce the mass spectrum.

expegt Heuristics programming was a major approach and a giant step forward in artificial intelligence, [4] as it allowed scientists to finally automate certain traits of human intelligence.
