3500/22M 138607-01 he latest version of the Suga solver COPT 7.0 is officially released. The upgraded COPT version 7.0 greatly improves the performance of the mixed integer programming and second-order cone programming solvers, further improves the speed and stability of linear programming and other solving modules, and has achieved 6 first and 4 second results in the ASU evaluation list of third-party mathematical optimization software evaluation platform. Among them, the optimal numerical solution and optimal vertex solution of linear programming are ranked first in the world, SOCP ranking first in the world, and MIP ranking second in the world.
At the same time, COPT 7.0 adds the online License authorization mode, which expands the COPT deployment mode and3500/22M 138607-01  provides flexible and fast choices for cloud usage scenarios such as enterprise production.
New users are welcome to visit Sugigu official website to apply for the latest COPT version. Existing users need to reinstall COPT and update the license file. As a feedback to the majority of users, for academic users, after re-applying will again get 365 days free trial permission.
Mixed integer programming (MIP) solver performance breakthrough, overall ahead of CPLEX
Mixed integer programming solver is widely used in practice, and the development difficulty is much higher than that of other modules such as linear programming, so the MIP solving performance is also an important standard that the industry pays most attention to and evaluates the optimization software level. COPT, which has been working on the module since its release, has finally achieved a breakthrough upgrade. According to the recent “data magician” released the evaluation results, the latest version of COPT 7.0, the solution performance has been significantly ahead of the European and American manufacturers CPLEX the latest version 22.1, not only can solve the number of problems more, and the relative solution time is 33% faster, which is also a milestone achievement in the development of domestic solvers.

3500/22M 138607-01  ASU Evaluation List is a third-party international authoritative mathematical optimization software evaluation platform maintained by Professor Hans Mittelmann of Arizona State University in the United States, in which representative practical problems in the industry are selected as examples, and the evaluation has been unanimously recognized by the solver industry. COPT 7.0 leads the ASU rankings, achieving six world first and four world second results. It is worth mentioning that for the second-order cone programming (SOCP) problem, which has an important and widely used scenario in the financial field, the solution performance of COPT version 7.0 has been greatly improved, exceeding the Danish manufacturer Mosek, which has specialized in this field for many years, and reaching the world’s first level. This is another breakthrough for COPT in nonlinear modules after MIQP module 6.5 surpassed Gurobi for the first time. The following is an introduction to the evaluation results of all COPT solving modules on the list: COPT’s online License (Web License) authorizes users to provide remote authorization services, whether the client is located in the cloud or in a container, as long as it can access the Internet through HTTPS. You can obtain a Token from the COPT Web License authorization server to run COPT without binding any hardware information and support cross-version use. Compared with the existing traditional authorization methods, online license is not limited to the fixed hardware environment, and provides fast and flexible support for service migration, switchover, and expansion in the cloud production environment of enterprises and universities.
In the traditional authorization mode, online License also includes three sub-categories: online Server License (Web license-server), online Floating License (Web license-floating), and online Cluster license (Web license-cluster).
1. Online Server License (Web license-server)
For personal trial and business users: Support the deployment of COPT servers in the cloud (without binding any machine hardware information), multiple modeling and solving tasks can be carried out on the server.
2. Online Floating License (Web license-floating)
For business users: Support the deployment of a floating token server in the cloud as a server (the server needs to connect to the Internet and obtain remote authorization through online licensing), and authorize other machines (clients) in the LAN to run COPT.
