mosdex-python

A Python demonstration of the MOSDEX standard for large-scale modular optimization problems. It is based on an experimental version of the MOSDEX Schema (version 1.3-ajk), which is still being refined. The MOSDEX standard is documented in the repository https://github.com/coin-modeling-dev/MOSDEX-Examples.

The schema is included in the data directory, along with a sailco file that tests it.

• To install the mosdex-python package and dependencies: pip install mosdex-python
• Example code is in the samples directory. To run sailco: cd samples; python -m sailco
• PDFs of some sample output are in mosdex-python/data

Wish list:

• Syntax to describe functional relationships between independent and dependent variables
• Syntax to describe sequence operators: next and previous
• Interfaces to some modeling languages
• Interfaces to COIN-OR/OSI libraries for integer, nonlinear, and stochastic dynamic optimization
• Implementations of decomposition algorithms
• Implementation of decomposition using distributed Cloud services
