In order to use a loop that keeps increasing the maximum number of iterations of the simplex method, is it possible to use a “max\_iter” parameter like the following sentence?  
“option gurobi\_options $gurobi\_options ’ iterlim=max\_iter’;”

For example, defining max\_iter like “param max\_iter integer default 50;” gives an error (Gurobi 10.0.2: Invalid “max\_iter” value for “lim:iter” option).

Thanks in advance,

Regards,  
Manuel
