DualBoundHistory not read for gurobi output #38

Closed leoneifler closed 7 years ago

leoneifler commented 7 years ago

When parsing a *.out file from a gurobi-run, dual bound history is empty.

debug_gurobi.out.txt

GregorCH commented 7 years ago

The dual bound history, so far, has been exclusively written for SCIP. If you want, @leoneifler , you can try to implement this yourself in the GurobiSolver class in ipet/parsing/Solver.py

leoneifler commented 7 years ago

Ok I will try to do that

GregorCH commented 7 years ago

Just make yourself familiar with how the SCIPSolver does it, and try to figure out the Gurobi peculiarities. If you happen to know a better parsing library to simplify that task, I am open to include this into IPET. Make sure that you use the Key module for providing the data key "DualBoundHistory".

If you have questions, post them here.

Ok that was easy, I just adapted how it works for gurobi primal history. Shall/Can I just push this to master or do you want me to create a new branch and merge that later?

The workflow here on github foresees that you

  1. create a fork of ipet
  2. create an experimental branch with the code changes in your fork
  3. create a pull request from your fork into ipet
