The solver_options_string is tricky because it often needs spaces between the flags to send to the solver. So you would usually put quotes around all the solver arguments to pass them as a single argument to Switch, like this:
--solver-options-string="mipgap=0.01 mipemphasis=0 mipbasis=1 nodefile=3 display=1 mipdisplay=2 threads=1 iisfind=1"
Not sure how my email will break that up, but --solver-options-string and the quoted string should all be on the same line, either in options.txt or on the command line.

What is the format in which I have to write for example: solver_options_string mipgap=0.001? I have tried many ways but it doesn't work for me.
Thank you very much.
