WebNov 26, 2024 · Prolog is “hardwired” to do depthfirst search, whereas doing breadthfirst requires you to manage the frontier list yourself. You invariably also end up having to manage the frontier list for depthfirst search to avoid hanging your computer if there are cycles (something tabling aims to solve, but I haven’t battled through its documentation yet). WebDec 3, 2024 · Consider the following graph and that it is described by the below Prolog term : graph ( [connected (a, [b,c]), connected (b, [a,c]), connected (c, [a,b,d]), connected (d, [c]) ]). I would like to define a predicate which transforms the above connections into a list of the corresponding pairs.
WebMay 8, 2013 · s/2 is a move; but we try new combinations through backtracking, so previous assignments are undone (forgotten). You'd have to change it: find all possible moves, in a list - then this list holds all the nodes to explore. BTW this particular solution is inefficient - it tries all queens from 1 to 8 on each move. but we don't need to try those that we already …
