A backtracking search for a solution to a CSP can be seen as performing a depth-first traversal of a search tree. The search tree is generated as the search progresses and represents alternative choices that may have to be examined in order to find a solution. The method of extending a no...
{T}\)are stored in an array as they are found the first time when the left-to-right depth-first-search traversal of the PS-tree is performed. In the triangulation of Fig.1, the ordered sequence of vertices stored in the array of vertices would be\(u_1\),\(u_2\),\(\ldots\),...
