## Solve linear inequalities calculator

In the optimization of large-scale communication network structure, the network optimization platform allocates network resources and improves user experience through network linear programming based on the traffic law of the whole network. In the large-scale cloud resource scheduling problem, the cloud scheduling platform combines the resources of various regions to balance the supply and demand of computing resources, support the business elasticity and meet the needs of business fluctuations under the condition of meeting the computing power, bandwidth and storage needs of customers, combined with predictive planning and network linear planning methods. In the future, the key technology of the network linear programming solver will also be applied to Huawei's digital energy optimization and scheduling problem, helping to solve the problem in minutes, improving energy utilization and reducing carbon emissions. It is a nonlinear problem to simulate an object with dynamically changing position and direction. However, the result of freezing a spatial configuration and solving the velocity is a linear system of equations. These equations are based on linearity, and there are inequality constraints between them, so in general, the linear complementarity problem (LCP) must be solved, which is still linear as its name indicates. The velocity space can be regarded as the tangent space of the nonlinear space of the space state in the current configuration. Therefore, it is more convenient to work in the linear space of speed than to directly deal with position and direction. However, one of the main disadvantages of this method is the drift problem, because the velocity solver cannot see the position error. Existing engines use various methods to solve this problem, such as introducing additional forces or constraints. Optimization problem is one of the most common problem types in mathematical modeling competition. Generally speaking, any goal that seeks the largest, smallest, farthest, nearest, most economical, richest, most efficient and most time-consuming can be included in the scope of optimization problems. The MATLAB optimization toolbox and the global optimization toolbox provide complete solutions to many optimization problems. The former covers solvers of linear programming, mixed integer linear programming, quadratic programming, nonlinear optimization and nonlinear least squares. The latter includes global search, multi initial points, pattern search, genetic algorithm and other solving algorithms. [highlight] this question examines the solution of abstract function inequalities, examines logical reasoning ability and operational solving ability. The key to solving is to study the properties of the constructor according to the inequality constructor given in the question, and then use the derivative to solve the inequality For large-scale network linear programming problems, especially those involving tens or even hundreds of millions of scale in actual scenarios, the underlying implementation is also the bottleneck of solver performance. Using the theoretical nature of network linear programming, Huawei's joint team has greatly optimized the underlying implementation of matrix library and other basic modules, and has greatly accelerated the solution process by using parallel technology, so that Huawei cloud chip AI solver can support the efficient solution of network linear programming on a scale of 100 million. When the inequality problem can not be solved by algebraic method, but it is related to function, it is often transformed into the upper and lower relationship problem of the image of two functions, and then solved by the combination of number and shape This ranking mainly competes for the speed of problem solving based on large-scale variables and constraints. Huawei's joint team proposed the adaptive sparsity optimization technology based on network topology characteristics and the underlying optimization and parallelization technology based on the theoretical nature of network linear programming problems. It achieved efficient solutions to 25 problems in the list, with performance leading the second place by 11%. The two technologies make full use of the structural characteristics of network linear programming problems, and greatly improve the performance of Huawei cloud chip AI solver on network linear programming problems.
