Dear GAMS friends,
I am using GAMS to implement a Column Generation Algorithm, GAMS gives me a solution that violate one of the implemented constraints.
capacity_limit_master(t)… sum(pk(i,k), proposalcapacity(i,t,k)*lambda(i,k)) =l= f(t)
I run GAMS, give me a solution, with the RHS=4 and LHS=7,
Any suggestion on how to solve this problem?
Thanks

I assume you want sum of (i,k) of proposalcapacity(i,t,k)*lambda(i,k)) < f(t). In that case I am not sure what the pk is for in designated sum command below of pk(i,k). I would write the equation as - capacity_limit_master(t)… sum((i,k), proposalcapacity(i,t,k)*lambda(i,k)) =l= f(t).
This assumes that lambda(i,k) is not a variable as well.
