Discrete mathematics is the study of mathematical structures that can be considered "discrete" (in a way analogous to discrete variables, having a bijection with the set of natural numbers) rather than "continuous" (analogously to continuous functions).
Matching tables for corresponding exercises from the 5th, 6th, 7th and 7th global editions of Rosen's book Discrete Mathematics and its Applications, Chapter 1 on The Foundations: Logic and Proofs (Bilingual edition, Spanish/English) (Technical report). KDEM (Knowledge Discovery Engineering and Management).
In formal language theory, an alphabet, sometimes called a vocabulary, is a non-empty set of indivisible symbols/characters/glyphs, [1] typically thought of as representing letters, characters, digits, phonemes, or even words.
In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. [1] A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.
Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic [1] – do not vary smoothly in this way, but have distinct, separated values.

In mathematics, what is termed binary tree can vary significantly from author to author. Some use the definition commonly used in computer science, [ 7 ] but others define it as every non-leaf having exactly two children and don't necessarily label the children as left and right either.
A demo for Prim's algorithm based on Euclidean distance. In computer science, Prim's algorithm is a greedy algorithm that finds a minimum spanning tree for a weighted undirected graph.
Dichotomization is the special case of discretization in which the number of discrete classes is 2, which can approximate a continuous variable as a binary variable (creating a dichotomy for modeling purposes, as in binary classification). Discretization is also related to discrete mathematics, and is an important component of granular computing.
