Discrete Structures, discrete mathematics is the study of basically not continuous mathematical structures. Unlike real numbers that have a "smooth" contrast property, the things that are taught in discrete mathematics - such as whole numbers, graphs, and data in logic - do not differ smoothly in this way, but have separate and separate values.

More formally, discrete mathematics is distinguished as a branch of mathematics that deals with countable groups (groups with the same origin in subsets of natural numbers, including logical numbers but not real numbers).

However, there is no precise definition of the term "discrete mathematics". In fact, discrete mathematics is less described with what is included than what is excluded: ever-changing quantities and related ideas.

### Discrete Structures

The set of objects studied in discrete mathematics can be limited or unlimited. The term-limited mathematics is sometimes applied to parts of the discrete mathematics field dealing with finite groups, especially those related to business.

On the contrary, computer applications are important in applying ideas from discrete mathematics to real-world problems, as in operations research.

Although the main things to study in discrete mathematics are separate objects, analytical methods from continuous mathematics are also used.

In university curricula, "discrete mathematics" appeared in the 1980s, initially as a course in support of computer science; Its contents were somewhat random at the time.

The curriculum was subsequently developed in conjunction with the efforts of ACM and MAA in a course mainly aimed at developing mathematical maturity among new students, and thus is at present a prerequisite for mathematics majors in some universities as well.

Some separate mathematics books also appeared in secondary schools. At this level, discrete mathematics is sometimes seen as a preparatory course, not unlike simulation in this regard.

Graphs such as the graphic above are one of the subjects studied in discrete mathematics, due to their mathematical properties, their benefits in solving real-world problems, and their importance in improving computational algorithms.

In mathematics, a countable group is a group whose elements can be attributed to one of the numbers of the set of natural numbers. This natural number represents the order of that element in the set. The first to use this term is George Cantor.

A group is considered numbered if the number of its elements is terminated or if it contains the same number of elements as the set of natural numbers.

Another definition of Cantor was that the group would be numbered if its elements could be interviewed one by one with a subset of the natural numbers.

Since natural numbers are always used for the purpose of counting, any group that exceeds this group by size is considered a group that cannot be counted. Different sizes of infinite sets of ordinal number theory specialization.

A group of things studied in discrete mathematics can be finite or infinite. The term-limited mathematics is sometimes applied to parts of the discrete mathematics field dealing with specific groups, especially those business-related fields.

### Major challenges, past and present

Much of the research in graph theory was motivated by attempts to demonstrate that all maps, such as these, can be tinted using only four colors so that no regions of the same color share an edge. Kenneth Abel and Wolfgang Hacken demonstrated this in 1976.

Computer engineering was an important part of computer graphics incorporated into modern electronic games and computer-aided design tools.

Many areas of discrete mathematics, especially theoretical computer science, graph theory, and harmonic, are important in facing the bioinformatics challenge of problems associated with understanding the tree of life.

Currently, one of the most well-known open problems in theoretical computer science is the P = NP problem which involves the relationship between the complexity categories P and NP. The Clay Mathematics Institute has offered a US \$ 1 million prizes for its first true guide, along with prizes for six other mathematical problems.
