  2. Social complexity - Wikipedia

    en.wikipedia.org/wiki/Social_complexity

    In sociology, social complexity is a conceptual framework used in the analysis of society. In the sciences, contemporary definitions of complexity are found in systems theory , wherein the phenomenon being studied has many parts and many possible arrangements of the parts; simultaneously, what is complex and what is simple are relative and ...

  3. Mathematical sociology - Wikipedia

    en.wikipedia.org/wiki/Mathematical_sociology

    The linkage of mathematics and sociology here involved abstract algebra, in particular, group theory. [12] This, in turn, led to a focus on a data-analytical version of homomorphic reduction of a complex social network (which along with many other techniques is presented in Wasserman and Faust 1994 [ 13 ] ).

  4. Computational complexity theory - Wikipedia

    en.wikipedia.org/.../Computational_complexity_theory

    Continuous complexity theory can also refer to complexity theory of the use of analog computation, which uses continuous dynamical systems and differential equations. [18] Control theory can be considered a form of computation and differential equations are used in the modelling of continuous-time and hybrid discrete-continuous-time systems.

  5. Hamiltonian path problem - Wikipedia

    en.wikipedia.org/wiki/Hamiltonian_path_problem

    The Hamiltonian path problem and the Hamiltonian cycle problem belong to the class of NP-complete problems, as shown in Michael Garey and David S. Johnson's book Computers and Intractability: A Guide to the Theory of NP-Completeness and Richard Karp's list of 21 NP-complete problems. [2] [3]

  6. NP (complexity) - Wikipedia

    en.wikipedia.org/wiki/NP_(complexity)

    In computational complexity theory, NP (nondeterministic polynomial time) is a complexity class used to classify decision problems. NP is the set of decision problems for which the problem instances , where the answer is "yes", have proofs verifiable in polynomial time by a deterministic Turing machine , or alternatively the set of problems ...

  7. Bifurcation theory - Wikipedia

    en.wikipedia.org/wiki/Bifurcation_theory

    Bifurcation theory has been applied to connect quantum systems to the dynamics of their classical analogues in atomic systems, [6] [7] [8] molecular systems, [9] and resonant tunneling diodes. [10] Bifurcation theory has also been applied to the study of laser dynamics [ 11 ] and a number of theoretical examples which are difficult to access ...

  8. PP (complexity) - Wikipedia

    en.wikipedia.org/wiki/PP_(complexity)

    The quantum complexity class BQP is the class of problems solvable in polynomial time on a quantum Turing machine. By adding postselection , a larger class called PostBQP is obtained. Informally, postselection gives the computer the following power: whenever some event (such as measuring a qubit in a certain state) has nonzero probability, you ...

  9. Complexity theory - Wikipedia

    en.wikipedia.org/wiki/Complexity_theory

    Computational complexity theory, a field in theoretical computer science and mathematics; Complex systems theory, the study of the complexity in context of complex systems; Assembly theory, a way of characterizing extraterrestrial molecular complexity to assess the probability of the presence of life
