WebDepth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes … http://staff.fit.ac.cy/com.ph/ai/AI_Lecture_2.pdf

First, Prolog's execution strategy is already a form of search. It is called depth-first search with chronological backtracking and can be regarded as a special case of resolution. Prolog is eminently well-suited for solving search tasks already due to this efficient built-in ...

WebThe execution of Prolog is done via depth- first backward chaining. A Prolog program can be executed in two modes: interpreted and compiled. Interpretation amounts to running the FOL-BC-Ask algorithm with the program as the knowledge base. Prolog interpreters can contain a variety of improvements to maximize speed and efficiency. WebBottom-up evaluation of logic programs offers well-known advantages over topdown: programs terminate if they have the finite term-depth property (as defined in ); redundant subcomputations are eliminated; and non-stratified programs can be evaluated according to the well-founded semantics without the possibly exponential number of negative contexts …
