Re: [Help-glpk] Sum inside for

[Nilo Cesar Teixeira]

Ok I figured it out by the prod.mod in the examples =)

s.t. r  {D1 in DIMENSION1, D2 in DIMENSION2, D3 in DIMENSION3} : sum {D4 in DIMENSION4} H[D1, D2, D3, D4] <= 1;

Hi again guys,

I am trying to model a loop in 4 dimensions, in which for each possible fixed tuple of the first 3 dimensions, the sum of the values of the 4 dimension must be at most 1.

Every cell is, again, a binary variable.

Something like this:

for {D1 in DIMENSION1, D2 in DIMENSION2, D3 in DIMENSION3} {

s.t. r: sum {D4 in DIMENSION4} H[D1, D2, D3, D4] <= 1;

}

But then I found that constraints are not permitted inside fors.

Why ? How to procede then ?

Thanks again.
