Hi
I just downloaded Symphony and tried using Interactive Optimizer. Whatever, I have been doing, input file is not getting read
"Input file '1.lp' can't be opened"
How to set directory and make it work?
I downloaded the following: COIN-OR-1.7.4-win32-msvc10
Regards
Sunil

When you specify a path in Windows, you have to use two backslashes as a separator for directories instead of just one, since otherwise, the backslashes causes the following characters to be escaped in the string when it's read. This is a universal problem with reading paths on Windows, see, e.g.,
this. This should work in the interactive solver.
