User story

As a user, I want to be able to import problems from MPS file to easily transition from known vendors to lava.

Conditions of satisfaction

• A MPS file can be read and a OptimizationProblem is returned
• The returned OptimizationProblem can be solved using lava-optimization
• Errors are raised if the problem is currently not solvable in lava-optimization
• Optimally, this allows integration of lava-optimization into Pyomo
• Optional: Problems can be exported to MPS files

Acceptance tests

• Test if a MPS file containing a QUBO problem is successfully read and solved
• Test if a MPS file containing a QP problem is successfully read and solved
• Test raises exceptions if a problem is read with is not solvable
• Optional: Test if a problem can be written to MPS

Tasks

• Get familiar with MPS file format and existing libraries for import/export (smps library)
• Obtain (or export from Gurobi) an example QUBO problem to MPS
• Implement a test for importing a MPS file and solving the problem
• Implement a prototype to import a MPS file to lava-optim
• Code review
