how can I model the incremental summation of one variable in GAMS cinstraints like the following: y(t) is variable; t is period index that t=1,…,4; in constriants section I want this summation in each period: t=1 : y(t=1) < t * 10 t=2 : y(t=2) < t * 10 – y(t=1) t=3 : y(t=3) < t * 10 – y(t=2) – y(t=1) t=4 : y(t=3) < t * 10 – y(t=3) – > y(t=2) – y(t=1)
