I have just downloaded latest Ampl bundle.
I tried to solve a lp using cbc as solver.
I modified cbc options : option cbc_options ‘outlev=2 ratioGap=0.1 allowableGap=0’;
But ratioGap and allowableGap did not seem to be taken into account.
The log was :
ampl: option cbc_options 'outlev=2 ratioGap=0.1 allowableGap=0'; ampl: solve; cbc 2.10.7: tech:outlev=2 double:ratioGap=0.1 double:allowableGap=0 Welcome to the CBC MILP Solver Version: 2.10.7 Build Date: Feb 27 2023 command line - Cbc_C_Interface -/ 0 -log 2 -solve -quit (default strategy 1) No match for / - ? for list of commands No match for 0 - ? for list of commands logLevel was changed from 1 to 2
I think there is something wrong with the command line.
