[Help-glpk] expressing a constraint depending on a boolean variable

[esma mehiaoui]

Hello everyone,

Please could you help me to express the following constraint if possible.

for i in {1..2} if V[i] =1 then 2<= sum {x in MySet} V2[x] <=3

                    else (V[i] =0) then sum {x in MySet} V2[x]  may have any value (i do not care about the value in this case)

with V and V2 are boolean variables

Thank you in advance

Esma
