67 results about "Problem domain" patented technology

A problem domain is the area of expertise or application that needs to be examined to solve a problem. Focusing on a problem domain is simply looking at only the topics of an individual's interest, and excluding everything else. For example, when developing a system to measure good practice in medicine, carpet drawings at hospitals would not be included in the problem domain. In this example, the domain refers to relevant topics solely within the delimited area of interest: medicine.

Formal sequential lagrangian algorithm for large scale resource scheduling optimization

ActiveUS20060089864A1Reduce operating costsFast dual optimization—obtainingDigital computer detailsForecastingProblem domainAlgorithm
A method and computer program product for optimization of large scale resource scheduling problems. Large scale resource scheduling problems are computationally very hard and extremely time consuming to solve. This invention provides a Lagrangian relaxation based solution method. The method has two distinct characteristics. First, the method is formal. It is completely structure-based and does not use any problem domain specific knowledge in the solution process, either in the dual optimization or the primal feasibility enforcement process. Second, updating the Lagrangian multipliers after solution of every sub-problem without using penalty factors results in fast and smooth convergence in the dual optimization. The combination of high quality dual solution and the structure-based primal feasibility enforcement produces a high quality primal solution with very small solution gap. An optimal solution is first found to the dual of the resource scheduling problem by sequentially finding a solution to a plurality of sub-problems and updating a set of values used in the dual problem formulation after each sub-problem solution is obtained. Coupling constraint violations are systematically reduced and the set of values are updated until a feasible solution to the primal resource scheduling problem is obtained. An initial set of multiplier values is further determined by solving a relaxed version of the primal problem where most of the local constraints except the variable bounds are relaxed.

Optimal transportation meshless method for solving large deformation of material

ActiveCN106446432AResolving Tensile Stress InstabilityAvoid high computationDesign optimisation/simulationSpecial data processing applicationsProblem domainMetallic materials
The invention relates to an optimal transportation meshless (OTM) method for solving large deformation of a material and aims at solving the problems of effective and stable solving of maximum deformation, high-speed impact and geometric distortion, metal material molding, multiphase coupling and the like. The OTM method adopts a material point and node pair original problem domain to perform discretion and adopts a local maximum entropy interpolation function to construct a continuous movement function, and the problem that mesh distortion caused in maximum deformation processed by adopting a finite element method, the problem that a Dirichlet boundary condition cannot be directly added for a meshless method, calculating misconvergence and the like are avoided. In addition, due to the fact that interpolation and integration are performed at different discrete points, an effective meshless numerical integration mode is provided, and the problem of tensile stress instability is solved. The OTM method serves as an incremental updating Lagrangian method to make mass conservation automatically achieved without solving. Time discretion is performed by adopting an optimal transportation theory, the momentum conservation and symplectic conservation of a discrete system are ensured, and the operation efficiency and precision are greatly improved.
