hello,

*I’m new in gams trying to implement the fallowing toy model.*

set c(e,e);

c(e,e) = not sameas(e,e);

set d(t,t);

d(t,t) = not sameas(t,t);

binary variables

x(e,t)

delta(e,e,i);

delta.l(e,e,i) = 0;

*I have 2 binary variables. I assigned delta to 0 initially.*

logc(c(e,e),d(t,t))…x(e,t)+x(e,t)-1=l=delta(e,e,i);

*for the " i " I need an equation like i=t-t
How can I do that?*
