COPT 5.0

既にEvaluation　Licenseは切れたのですが、次のメールを受領しました。急速にMIP　Solverの性能が向上しているようです。Mittelmannベンチマーク、がGurobiに対して２．３４倍の遅さというのは、素晴らしいと思います。また、表によれば、HighsがほぼSCIPと同じ性能を示しており、こちらも急速に力をつけています。SCIPの行数、確か数十万行に対してHighsは、数万行に満たない思うのでこちらも健闘していると思います。

 

We are excited to announce that COPT 5.0 has been released on June 20, 2022, with the following highlights:

 

 - Improved COPT MIP solver performance by 50%  

 - Added COPT SDP solver, which outperforms all existing SDP solvers  

 - Added a FeasRelax utility

COPT 5.0 takes the leading position in several benchmark measurements, as shown in the summary below (based on results from [a:http://plato.asu.edu/bench.html]Benchmarks for Optimization Software maintained by Hans Mittelmann, date: June 26, 2022):
