comment have value of variable take on whether two other variables equal?
I can't use if() statements on variables, and where is c in your equation?

comment have value of variable take on whether two other variables equal?
I personally am using ZIMPL and SCIP. But if it can be expressed generically, I am sure I can translate it to the proper language.

comment possible to index a set by a variable?
I guess in my mind what I'm trying to do isn't difficult, but it's difficult in the realm of the LP. I'm really just trying to fetch a specific value based on the value of a variable. I thought I could contain them in a set and index them based on the variable, but I can't. Really looking for any other way to do something similar.

Is there a linear way that you can think of for b to take on the value that I want it to take on? I'm stuck trying to figure out some other way to represent this.

Great! Sorry for the constant typo in your username, it's Apple's autocorrect at work. Fixed.
