HiGHS Implementation and Documentation
zepedropaulos opened this issue · comments
PuLP's documentation states that HiGHS_CMD
contains a gapRel
and threads
parameters. However, the built-in HiGHS_CMD
does not, on pulp v2.7.0. The version available here (https://github.com/coin-or/pulp/blob/master/pulp/apis/highs_api.py) does contain these parameters, but the version installed via PyPi, does not.
The function contains only an option
parameter, but it always returns errors when parsing the options. Already tried several things, but none seems to be working:
milp.setSolver(HiGHS_CMD(msg=True, timeLimit=100, path=highs_path, threads=1))
milp.setSolver(HiGHS_CMD(msg=True, timeLimit=100, path=highs_path, options="threads=1"))
milp.setSolver(HiGHS_CMD(msg=True, timeLimit=100, path=highs_path, options=["threads=1"]))
milp.setSolver(HiGHS_CMD(msg=True, timeLimit=100, path=highs_path, options=["--threads=1"]))
milp.setSolver(HiGHS_CMD(msg=True, timeLimit=100, path=highs_path, options=["--threads","1"]))
milp.setSolver(HiGHS_CMD(msg=True, timeLimit=100, path=highs_path, options=["--options_file","highs_options.txt"]))
milp.setSolver(HiGHS_CMD(msg=True, timeLimit=100, path=highs_path, options=["--options_file","highs_options.txt"]))
How are we supposed to parse the options?
Thanks for the report. Indeed, we've just released a new pulp version that should solve this. If it doesn't, please re-open it.
