What is the 'Horizon Effect' in game-playing heuristic search programs?
The horizon effect occurs when a fixed-depth search postpones an inevitable disadvantage beyond its search horizon using stalling moves, mistakenly believing it avoided damage.
In production rule-based expert systems, which pattern-matching algorithm is widely used to efficiently match facts in working memory against rule conditions?
Charles Forgy developed the Rete algorithm, which builds a directed acyclic network of condition nodes to eliminate redundant evaluations across rules in production systems.
In production systems, what is the term for the process of selecting which rule to fire when multiple rule preconditions match the current working memory?
Conflict resolution strategies (e.g., salience/priority, specificity, recency) decide which single rule to execute from the active conflict set.
Which historic expert system developed at Stanford in the 1960s inferred molecular chemical structures from mass spectrometry organic data?
DENDRAL was the expert system for chemical molecular structure inference. Since DENDRAL is not listed, (E) is the correct answer.
In AI terminology, what characterizes a 'Static' environment versus a 'Dynamic' environment?
Both statements (A) and (B) correctly define static and dynamic agent environments.
