What means "Warning: 1 variables dropped from basis"

    Hi Jonathan, 

    The warning message means that the basis became singular. Therefore, the columns involved in the singularity (1 column in your case) needed to be dropped and replaced by another column. Gurobi would then switch to a higher precision to recover the basis and to avoid such a situation as much as possible in the rest of the run. 

    Best regards,
