Benjamin McCann updated MATH-246:
---------------------------------

    Attachment: large.test

Anders Hessellund contacted me about solving a model with 216 variables.  I coded up his problem as a test case below and it correctly arrived at a solution given to me by another tool, which gives me confidence in the code.
Luc, thanks for following up about the paperwork.  I had tried last week, but couldn't reach people out on vacation.
