Octeract Engine
Octeract Engine is a proprietary massively parallel deterministic global optimization solver for general Mixed-Integer Nonlinear Programs (MINLP).
The solver is designed to work in parallel on a distributed environment. It is optimized for succeeding in synthetic benchmark sets. The latest world records were set in April 2023, when it became the first optimization solver to ever solve all problems in the benchmark, with a world record setting unscaled shifted geometric mean of 36.8.
Octeract Engine was developed by Nikos Kazazakis and Gabriel Lau. The first public beta version of Octeract Engine was released in August 2019, and it came out of beta in August 2020.
On 23 July 2022 it ranked first on the single thread Mittelmann MINLPLIB benchmark. This lead has been maintained for all releases of Octeract Engine hence.
As of August 2022 it is the first and only solver to solve the largest open transmission switching problems in the industry standard MINLPLIB library, namely transswitch2736spp and transswitch2736spr.
Octeract Engine currently holds two world records in MINLP benchmarks. The first world record, set on 20 April 2023, is in number of problems solved (100%). The second world record, also set on 20 April 2023, is the smallest unscaled shifted geometric mean ever achieved for this test set, which was 36.8. The runner-ups achieved means of 138.2 (BARON) and 380.5 (SCIP), with Couenne ranking last with a mean of 3304.4.
On 27 October 2022 Octeract Engine set its first world record by solving more 91% of problems in the benchmark, which was more than any solver had ever been able to solve by that time. This record has yet to be broken by any other solver as of 21 April 2023.
In January 2023, it became the first solver to solve 99% of problems in this benchmark.
