About the project

This is the Operations Research tools suite developed by Google since 2015 (think tensorflow but for OR)
ref: https://developers.google.com/optimization

note:

• example data are not part of our package since we have more than 1Go of OR models...
• our native C++ package is bundle with all its dependencies (kind of follow https://peps.python.org/pep-0513/#the-manylinux1-policy i.e. no external dll deps)
• We are working on build shared lib on windows but symbols export make it more complicated than on unix system.

Reasons for the request

ortools is a native python package.
On unix we use a shared lib aka libortools.so (so macos and linux packages are ~25MB) while on windows we use/build as static library libortools.lib (to avoid mess with C++ import/export dll stuff)
unfortunately ortools is composed of a dozen of module using pybind11 which each link against the underlying libortools.lib making each modules having a .pyd with ~20Mo (pybind11 wrapper + (duplicated) ortools symbols) .

For the new release v9.9 we just add a new module (ortools.math_opt) increasing the windows wheel packages (3.8 to 3.12) to 108Mb hitting the 100MB limit...

ls -l
total 540M
-rw-r----- 1 corentinl primarygroup 108M Mar  6 10:34 ortools-9.9.3963-cp310-cp310-win_amd64.whl
-rw-r----- 1 corentinl primarygroup 108M Mar  7 08:49 ortools-9.9.3963-cp311-cp311-win_amd64.whl
-rw-r----- 1 corentinl primarygroup 108M Mar  7 09:17 ortools-9.9.3963-cp312-cp312-win_amd64.whl
-rw-r----- 1 corentinl primarygroup 108M Mar  5 17:35 ortools-9.9.3963-cp38-cp38-win_amd64.whl
-rw-r----- 1 corentinl primarygroup 108M Mar  5 18:03 ortools-9.9.3963-cp39-cp39-win_amd64.whl

So I am requesting a increase up to 125Mb in order to be able to publish our windows .whl artifacts...

note: In parallel we are working on trying to move to a shared common lib libortools.dll like on linux/macos wheel packages for windows in order to reduce the size to ~30MB but this may need few months and we would like to release our v9.9 before...
