Max operator in MINLP

Post by priyanka_shinde »

I am trying to model MINLP formulation in which I need to use max operator to find the maximum between two values like max(a,b) so it should either give a or b depending on whichever is maximum. However, in my model a is a variable and b is constant value so can someone suggest me how to use max function so that I get the desired output. Right now I have just tried writing max(a,b) but that doesn't work.

Regards,
Priyanka
