  2. List of NP-complete problems - Wikipedia

    en.wikipedia.org/wiki/List_of_NP-complete_problems

    Dominating set, a.k.a. domination number [3]: GT2 NP-complete special cases include the edge dominating set problem, i.e., the dominating set problem in line graphs. NP-complete variants include the connected dominating set problem and the maximum leaf spanning tree problem. [3]: ND2 Feedback vertex set [2] [3]: GT7

  3. Partition function (statistical mechanics) - Wikipedia

    en.wikipedia.org/wiki/Partition_function...

    As an example: the partition function for the isothermal-isobaric ensemble, the generalized Boltzmann distribution, divides up probabilities based on particle number, pressure, and temperature. The energy is replaced by the characteristic potential of that ensemble, the Gibbs Free Energy .

  4. Combinatorics - Wikipedia

    en.wikipedia.org/wiki/Combinatorics

    Combinatorics is an area of mathematics primarily concerned with counting, both as a means and as an end to obtaining results, and certain properties of finite structures.It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science.

  5. Cluster expansion - Wikipedia

    en.wikipedia.org/wiki/Cluster_expansion

    In statistical mechanics, the cluster expansion (also called the high temperature expansion or hopping expansion) is a power series expansion of the partition function of a statistical field theory around a model that is a union of non-interacting 0-dimensional field theories.

  6. Partition function (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Partition_function...

    Given a set of random variables taking on values , and some sort of potential function or Hamiltonian (,, …), the partition function is defined as = ⁡ ((,, …)) The function H is understood to be a real-valued function on the space of states {,,}, while is a real-valued free parameter (conventionally, the inverse temperature).

  7. Isothermal–isobaric ensemble - Wikipedia

    en.wikipedia.org/wiki/Isothermal–isobaric_ensemble

    Constant-pressure simulations are useful for determining the equation of state of a pure system. Monte Carlo simulations using the -ensemble are particularly useful for determining the equation of state of fluids at pressures of around 1 atm, where they can achieve accurate results with much less computational time than other ensembles.

  8. Set splitting problem - Wikipedia

    en.wikipedia.org/wiki/Set_splitting_problem

    For k ≥ 4, Ek-Set Splitting is approximation resistant. That is, unless P=NP, there is no polynomial-time (factor) approximation algorithm which does essentially better than a random partition. [5] [6] The weighted set splitting is a variant in which the subsets in F have weights and the objective is to maximize the total weight of the split ...

  9. Partition coefficient - Wikipedia

    en.wikipedia.org/wiki/Partition_coefficient

    For example, the blood/gas partition coefficient of a general anesthetic measures how easily the anesthetic passes from gas to blood. [5] Partition coefficients can also be defined when one of the phases is solid, for instance, when one phase is a molten metal and the second is a solid metal, [6] or when both phases are solids.
