Help with conditional formatting

GAMS

Hi all,

I have two sets R = {r1, r2, … , r10} and G = {g1, g2, … , g10}. For all g in G, g is either a 1 or a 0.

I want to write:

if g1 =0 and g2 = 0, then r1 = 0, or something similar for each element in G and R.

I think I write it like this: r1$(g1=0 AND g2=0)=0.

But I keep getting errors. Also, I’m not sure if this expression should be listed as a parameter or as an equation. Any ideas?

Thanks,

Kevin

hi,
“r1” is member of Set. So, why you want to assign zero value?!
r1$(g1=0 AND g2=0)=0
The above term is completely wrong!
