Peter Smith's very useful LaTeX for Logicians page offers suggestions both for downward branching proof-trees and for natural deduction proofs in both Gentzen sequent-style (the tree-like style you seem to be after) and Fitch-style. I've not used any of the alternatives for proof trees, as I use Fitch-style natural deduction proofs.

What are Parse Trees (Derivation Trees) - TutorialsPoint

WebDerivation is a sequence of production rules. It is used to get the input string through these production rules. During parsing, we have to take two decisions. These are as follows: We have to decide the non-terminal which is to be replaced. We have to decide the production rule by which the non-terminal will be replaced.

WebA grammar may have an unbounded number of derivation trees. It just depends on which production is expanded at each vertex. For any valid derivation tree, reading the leafs from left to right gives one string in the language defined by the grammar. There may be many derivation trees for a single string in the language.

WebIn computer science, an ambiguous grammar is a context-free grammar for which there exists a string that can have more than one leftmost derivation or parse tree.
