The COIN-OR Foundation is seeking support to continue providing open-source optimization software for the operations research community. They have published an article, Future of COIN-OR, describing their challenges in securing funding and the participation of community members to continue operating.
COIN-OR are responsible for the development of more than 70 projects that are widely used in optimization tools, including:
- Pyomo, a Python-based optimization modeling language.
- PuLP, a Python library for linear optimization.
- CBC, the default mixed integer linear programming solver used in OpenSolver and elsewhere.
- Bonmin and Couenne, non-linear mixed integer programming solvers.
The COIN-OR Foundation presents three possible future directions:
Option 1: Wind down the COIN-OR Foundation activities related to maintenance and development of common infrastructure and existing codes that are not otherwise maintained.
Option 2: Continue operating in a haphazard fashion and hope that the community will eventually take up the cause as things slowly degrade.
Option 3: Find a path to funding the current activities of the COIN-OR Foundation in a sustainable way.
