We examine combinatorial objects of pyramidal structure. We consider one of the ways of representing rules in hierarchical, sequential structures: the method of decision trees, where each object corresponds to a single node that provides a solution. An algorithm for constructing a decision tree based on the generalized Pascal pyramid is suggested. Also, we propose a method for constructing a search index, which displays the proportion of relevant material and allows one to perform comparisons in the variety of terms based on the weight coefficients of terms and paths.
Keywords: hierarchical structure, partially ordered set, generalized Pascal pyramid, decision-making problem, decision tree, combinatorial algorithm.
