  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. Mathematical optimization - Wikipedia

    en.wikipedia.org/wiki/Mathematical_optimization

    A problem with continuous variables is known as a continuous optimization, in which optimal arguments from a continuous set must be found. They can include constrained problems and multimodal problems. An optimization problem can be represented in the following way:

  4. 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 ...

  5. 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).

  6. 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.

  7. Hill climbing - Wikipedia

    en.wikipedia.org/wiki/Hill_climbing

    In numerical analysis, hill climbing is a mathematical optimization technique which belongs to the family of local search. It is an iterative algorithm that starts with an arbitrary solution to a problem, then attempts to find a better solution by making an incremental change to the solution. If the change produces a better solution, another ...

  8. 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 ...

  9. Barrier function - Wikipedia

    en.wikipedia.org/wiki/Barrier_function

    A barrier function, now, is a continuous approximation g to c that tends to infinity as x approaches b from above. Using such a function, a new optimization problem is formulated, viz. minimize f(x) + μ g(x) where μ > 0 is a free parameter. This problem is not equivalent to the original, but as μ approaches zero, it becomes an ever-better ...
