problem relaxation
1Relaxation (approximation) — In mathematical optimization and related fields, relaxation is a modeling strategy. A relaxation is an approximation of a difficult problem by a nearby problem that is easier to solve. A solution of the relaxed problem provides information about… …
2relaxation phenomenon — ▪ physics and chemistry Introduction in physics and chemistry, an effect related to the delay between the application of an external stress to a system that is, to an aggregation of matter and its response. It may occur in nuclear, atomic,… …
3Cutting Stock Problem — Das eindimensionale Zuschnittproblem (engl. one dimensional cutting stock problem) ist ein schweres ganzzahliges lineares Optimierungsproblem mit dem Ziel, eindimensionale Teile in vorgegebenen Bedarfszahlen aus möglichst wenig Stücken Material… …
4Linear programming relaxation — In mathematics, the linear programming relaxation of a 0 1 integer program is the problem that arises by replacing the constraint that each variable must be 0 or 1 by a weaker constraint, that each variable belong to the interval [0,1] .That is,… …
5Lagrangian relaxation — In the field of mathematical optimization, Lagrangian relaxation is a relaxation method which approximates a difficult problem of constrained optimization by a simpler problem. A solution to the relaxed problem is an approximate solution to the… …
6Dual problem — In constrained optimization, it is often possible to convert the primal problem (i.e. the original form of the optimization problem) to a dual form, which is termed a dual problem. Usually dual problem refers to the Lagrangian dual problem but… …
7LP-Relaxation — Als LP Relaxation (abgeleitet von Lineare Programmierung) wird bezeichnet, wenn bei einem Problem der ganzzahligen linearen Optimierung die Forderung der Ganzzahligkeit aufgegeben wird. So ersetzt man z.B. Nebenbedingungen der Gestalt des… …
8Jacobson's Progressive Muscle Relaxation — Progressive muscle relaxation (or PMR) is a technique of stress management developed by American physician Edmund Jacobson in the early 1920s. Jacobson argued that since muscular tension accompanies anxiety, one can reduce anxiety by learning how …
9Closure problem — A Closure problem is a problem in graph theory for finding a set of vertices in a directed graph such that there are no edges from the set to the rest of the graph. More specifically, the minimum closure problem asks for a set of this type with… …
10Constraint satisfaction problem — Constraint satisfaction problems (CSP)s are mathematical problems defined as a set of objects whose state must satisfy a number of constraints or limitations. CSPs represent the entities in a problem as a homogeneous collection of finite… …
