Hello,

I am new with GAMS and i have been trying to write a code for :

productory from i different of b (ps)^f

All the prod examples that i have seen are productory from i.

I have not been able to get it done, does any one knows how to do

it??

If anyone knows please help me.

Thank you,

hi

i am not sure if i understand you or not , but i think you want to get

the product of a term with subscripts i and b, such that i is not

equal to b.

if this is your problem , you can write the code as follows:

prod((I,b) (ord (i) ne ord(b)), your term(I,b))
If you want to run it such that I is less than b, it will become:
prod((I,b) (ord (i) lt ord(b)), your term(I,b))

i hope it is usefull for you

best regards
