  2. Optimization problem - Wikipedia

    en.wikipedia.org/wiki/Optimization_problem

    An optimization problem with discrete variables is known as a discrete optimization, in which an object such as an integer, permutation or graph must be found from a countable set. A problem with continuous variables is known as a continuous optimization, in which an optimal value from a continuous function must be found.

  3. Maximum theorem - Wikipedia

    en.wikipedia.org/wiki/Maximum_theorem

    The theorem is typically interpreted as providing conditions for a parametric optimization problem to have continuous solutions with regard to the parameter. In this case, Θ {\displaystyle \Theta } is the parameter space, f ( x , θ ) {\displaystyle f(x,\theta )} is the function to be maximized, and C ( θ ) {\displaystyle C(\theta )} gives ...

  4. Test functions for optimization - Wikipedia

    en.wikipedia.org/.../Test_functions_for_optimization

    The artificial landscapes presented herein for single-objective optimization problems are taken from Bäck, [1] Haupt et al. [2] and from Rody Oldenhuis software. [3] Given the number of problems (55 in total), just a few are presented here. The test functions used to evaluate the algorithms for MOP were taken from Deb, [4] Binh et al. [5] and ...

    An optimization problem with discrete variables is known as a discrete optimization, in which an object such as an integer, permutation or graph must be found from a countable set. A problem with continuous variables is known as a continuous optimization, in which optimal arguments from a

  6. Envelope theorem - Wikipedia

    en.wikipedia.org/wiki/Envelope_theorem

    In mathematics and economics, the envelope theorem is a major result about the differentiability properties of the value function of a parameterized optimization problem. [1] As we change parameters of the objective, the envelope theorem shows that, in a certain sense, changes in the optimizer of the objective do not contribute to the change in ...

  7. Continuous optimization - Wikipedia

    en.wikipedia.org/wiki/Continuous_optimization

    Continuous optimization is a branch of optimization in applied mathematics. [1]As opposed to discrete optimization, the variables used in the objective function are required to be continuous variables—that is, to be chosen from a set of real values between which there are no gaps (values from intervals of the real line).

  8. Cross-entropy method - Wikipedia

    en.wikipedia.org/wiki/Cross-Entropy_Method

    The cross-entropy (CE) method is a Monte Carlo method for importance sampling and optimization. It is applicable to both combinatorial and continuous problems, with either a static or noisy objective. The method approximates the optimal importance sampling estimator by repeating two phases: [1] Draw a sample from a probability distribution.

  9. Shekel function - Wikipedia

    en.wikipedia.org/wiki/Shekel_function

    A Shekel function in 2 dimensions and with 10 maxima. The Shekel function or also Shekel's foxholes is a multidimensional, multimodal, continuous, deterministic function commonly used as a test function for testing optimization techniques. [1] The mathematical form of a function in dimensions with maxima is:
