The truth values of logical formulas usually form a finite set, generally restricted to two values: Information theory The ASCII codes for the word "Wikipedia", given here in binaryprovide a way of representing the word in information theoryas well as for information-processing algorithms.

Included within theoretical computer science is the study of algorithms for computing mathematical results. The study of mathematical proof is particularly important in logic, and has applications to automated theorem proving and formal verification of software.

Combinatorics Combinatorics studies the way in which discrete structures can be combined or arranged. Theoretical computer science also includes the study of various continuous computational topics.

Closely related is coding theory which is used to design efficient and reliable data transmission and storage methods. In discrete mathematics, countable sets including finite sets are the main focus. For classical logic, it can be easily verified with a truth table. Partially ordered sets and sets with other relations have applications in several areas. Mathematical logic Logic is the study of the principles of valid reasoning and inferenceas well as of consistencysoundnessand completeness. Indeed, contemporary work in descriptive set theory makes extensive use of traditional continuous mathematics.

Several fields of discrete mathematics, particularly theoretical computer science, graph theory, and combinatoricsare important in addressing the challenging bioinformatics problems associated with understanding the tree of life.

The Cold War meant that cryptography remained important, with fundamental advances such as public-key cryptography being developed in the following decades. The telecommunication industry has also motivated advances in discrete mathematics, particularly in graph theory and information theory.

InYuri Matiyasevich proved that this could not be done. In contrast with enumerative combinatorics which uses explicit combinatorial formulae and generating functions to describe the results, analytic combinatorics aims at obtaining asymptotic formulae. Computational geometry applies algorithms to geometrical problems, while computer image analysis applies them to representations of images. Operations research remained important as a tool in business and project management, with the critical path method being developed in the s.

Partition theory studies various enumeration and asymptotic problems related to integer partitionsand is closely related to q-seriesspecial functions and orthogonal polynomials. Order theory is the study of partially ordered setsboth finite and infinite. Analytic combinatorics concerns the enumeration i.

It draws heavily on graph theory and mathematical logic. In graph theory, much research was motivated by attempts to prove the four color theoremfirst stated inbut not proved until by Kenneth Appel and Wolfgang Haken, using substantial computer assistance. Originally a part of number theory and analysispartition theory is now considered a part of combinatorics or an independent field. Design theory is a study of combinatorial designswhich are collections of subsets with certain intersection properties. Computational geometry has been an important part of the computer graphics incorporated into modern video games and computer-aided design tools.

Enumerative combinatorics concentrates on counting the number of certain combinatorial objects - e. Information theory involves the quantification of information. Concepts such as infinite proof trees or infinite derivation trees have also been studied,  e.

Kenneth Appel and Wolfgang Haken proved this in Computability studies what can be computed in principle, and has close ties to logic, while complexity studies the time, space, and other resources taken by computations. Logical formulas are discrete structures, as are proofswhich form finite trees  or, more generally, directed acyclic graph structures   with each inference step combining one or more premise branches to give a single conclusion.

Formal verification of statements in logic has been necessary for software development of safety-critical systemsand advances in automated theorem proving have been driven by this need. Theoretical computer science includes areas of discrete mathematics relevant to computing.Discrete Math I – Practice Problems for Exam I The upcoming exam on Thursday, January 12 will cover the material in Sections 1 through 6 of Chapter 1.

By contrast, discrete math, in particular counting and probability, allows students—even at the middle school level—to very quickly explore non-trivial "real world" problems that are challenging and interesting.

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  – do not vary smoothly in this way, but have.
