Snapshot of master created on February, 8th, 2023.

• Synchronized links for HiGHS, Ipopt, SoPlex, and SCIP with those used by the GAMS distribution.
• New: Options initprimal and initdual for the AmplSolver link to control writing of initial values in AMPL .nl file.

The attached archives contain pre-build GAMS links for AmplSolver, Bonmin, Cbc, Couenne, HiGHS, Ipopt, SoPlex (new), and SCIP (new) and the corresponding solver libraries. Only a GAMS base license is required to use these.
The current development-version (master branch) of Cbc, Bonmin, and Couenne were used. HiGHS is version 1.4.2. Ipopt is version 3.14.11. SCIP is version 8.0.3. SoPlex is version 6.0.3.
The .md files contain lists of available solver options.

The links should work with a GAMS 42 system and maybe also some previous GAMS distributions.

See the included README for more details.

Snapshot of master created at May, 4th, 2022.

New: Link AmplSolver allows to run solvers for AMPL under GAMS, and get the solution back. The link writes an AMPL .nl file, calls the solver, and reads the AMPL .sol file.

The attached archives contain pre-build GAMS links for AmplSolver, Bonmin, Cbc, Couenne, HiGHS, and Ipopt and the corresponding solver libraries.
The current development-version (master branch) of Cbc, Bonmin, and Couenne were used. HiGHS is version 1.2.2. Ipopt is version 3.14.6.
The .md files contain lists of available solver options.

The links should work with a GAMS 39 system and maybe also some previous GAMS distributions.

See the included README for more details.

2022-02-09

Snapshot of master created at February, 9th, 2022.

The attached archives contain pre-build GAMS links for Bonmin, Cbc, Couenne, HiGHS, and Ipopt and the corresponding solver libraries.
The current development-version (master branch) of Cbc, Bonmin, and Couenne were used. HiGHS is version 1.2. Ipopt is version 3.14.5.
The .md files contain lists of available solver options.

The links should work with a GAMS 38 system and maybe also some previous GAMS distributions.

See the included README for more details.

2021-08-20

Snapshot of master created at August, 20th, 2021.

The attached archives contain pre-build GAMS links for Cbc, Ipopt, Bonmin, and Couenne and the corresponding solver libraries.
The current development-version (master branch) of Cbc, Bonmin, and Couenne were used. Ipopt is version 3.14.2.
The .md files contain lists of available solver options.

The links should work with a GAMS 36 system and probably also with some previous and future GAMS distributions.

See the included README for more details.

2020-08-20

Snapshot of master created at August, 20th, 2020.

The attached archives contain a pre-build GAMS link for Couenne and the corresponding solver libraries.
The current development-version (master branch) of Couenne was used.
optcouenne.md contains a list of available solver options.

The Couenne link works with a GAMS 32 system and probably also with some future GAMS distributions.

See the included README for more details.
