Introduction

在如今big data时代的浪潮中，运筹学进一步蓬勃发展，如何将大数据转化为最优决策成为其研究的重点课题。运筹学的应用场景是在满足约束条件下能够最大化、最小化单个或多个目标，从而得出最优决策。实现决策最优有两大关键步骤：建模，将问题通过数学形式准确有效地表达；求解，获得最优化目标函数的决策。在最优化目标函数求解过程中，很多实际问题受到大规模数据导致计算能力不足的影响，使得很好的模型不能发挥应有的实际效应。为了更好地解决求解问题，优化求解器（optimization solver）应运而生。目前，市面上知名的求解器有IBM旗下的CPLEX、FICO旗下的Xpress、Gurobi、MOSEK等。其中，丹麦MOSEK ApS公司开发的数学优化求解器MOSEK在求解二次规划、二阶锥和半正定规划等优化问题中，显示出强大的生命力。

MOSEK is a mathematical optimization solver developed by the Danish company MOSEK ApS for solving linear, mixed-integer linear, quadratic, mixed-integer quadratic, quadratically constrained, conic and convex nonlinear mathematical optimization problems. The applicability of the solver varies widely and it is commonly used to solve problems in areas such as engineering, finance and computer science. A special feature of the solver is its interior-point optimizer based on the so-called chi-square model.MOSEK's focus is on solving large-scale sparse problems, in particular linear, conic-quadratic (a.k.a. second-order conic programming), and semidefinite (a.k.a. semidefinite programming) interior-point optimizers, which are solved quite efficiently by the software.

Overall, MOSEK has the following technical advantages:

l Provide optimizationserver (computer)For remote optimization.

l Fully utilize the hardware features of multi-core processors forparallel computing.;

l The size of the problem that can be solved is limited only by the memory capacity of the computer;

l World-leading implementation of interior point methods for solving linear, second-order conic and quadratic programming problems;

l Provides programming interfaces based on Matrix and Fusion, including C, C++,Python,Java, C#, MATLAB, and R;

l Supports a variety of modeling environments, including commercial tools such as AMPL, GAMS and CVX, and open source tools such as CVXPY and JuMP;

l Supports multiple operating systems, includingWindows (computer),Linuxrespond in singingMacOS.;

MOSEK also has different commercial licenses for customers with various needs.

Institutional Academic License 

This is a floating license, which allows you to use several instances of MOSEK at the same time, through a License Server. It is designed specifically for universities, departments or university research groups The license is valid for two years and can be renewed any number of times through our website. Like the Personal Academic license, the request must be made using your academic email address. The license is valid for two years and can be renewed any number of times through our website. Like the Personal Academic license, the request must be made using your academic email address.

do not apply for an instantaneous licence if you do not need severe users' consentingly running matek in the same network.. Use a Personal Academic license instead. It is easier and faster to obtain.If you do not need multiple users running MOSEK on the same network at the same time, do not apply for an institutional license. Use a Personal Academic license instead. It is easier and faster to obtain.

A second email with the license key attachment is sent to our edu mailbox.

Dear user.

This email contains a Personal Academic License file valid until 2025-feb-22 for the MOSEK Optimization Tools version 10. This license is backward compatible, meaning it supports both current and earlier versions of MOSEK.

Although your license expires on the date above, Mosek allows you to submit a request for a new license up to 30 days before this date.

The license file should be placed inside a folder called "mosek" under the user's home directory ($HOME/ mosek/mosek.lic or %USERPROFILE%\mosek\mosek.lic). In most typical cases that will be.

/home/YOUR_USER_NAME/mosek/mosek.lic (Linux)
/Users/YOUR_USER_NAME/mosek/mosek.lic (OSX)
C:\Users\YOUR_USER_NAME\mosek\mosek.lic (Windows)


Where YOUR_USER_NAME is your user ID on the computer.

Troubleshooting

In this section of our documentation you will find more advanced options for locating the license file. Running a license debugging tool, such as " msktestlic" in the command line or "mosekdiag" in MATLAB, can help you resolve issues with the license path.

These instructions assume the OS environment variable MOSEKLM_LICENSE_FILE has not If the variable was changed, it should point to the license file location.

If you are a MATLAB user, remember to restart MATLAB after updating an existing license file. If you used the manual installer on Windows, ensure the folder with MOSEK binaries ( .../bin) is in the environment variable PATH.
