Hi,

I need to know how can I change the conversion of a variable more than once.
For example, I have a x1,x2 and x3 variables.

At first, the three variables are binary.

I need to relax x2 and x3 and solve the IP problem. After I need to put x2 and x3 how binary variables and solve again the problem.

In cplex, using Iloconversion, i obtain:

Concert exception caught: MultipleConversionException: IloCplex can not handle multiple variable type conversions

How can I do it?

Thanks a lot!!

Use an IloConversion to change a variable from binary to real. To restore it as binary, delete the conversion from the model (don't add a new conversion on top of it).
