How to handle variables determined by other variables?

GAMS

Hi,geeks:
In my project, Objection function is the sum of a series of binary
variables determined by other variables ,say if
variableA>variableB,the binary variable Flag1 = 1,otherwise Flag1=0.
What should I do?

Thanks

Model the objective function is no problem.
To model your constraint condition, you should model it approprieately, I sugest a reading in the following material:

Notice this is a Gams user list you should first have your problem well formulated before code it.
You can also try operations research discussion groups:
