@objective (m,Min,sum (LS [i, j]*C[i, j] for i, j ∈ 1:f))
How to make this expression read the for i,j. The way I did the error appears:
syntax: invalid iteration specification
You shouldn’t have spaces between a function name and the parenthesis or between the variable name and the bracket. I would have expected an ERROR: syntax: space before "[" not allowed type of message instead of the iteration message, but I would fix those and see if that gets you there or closer.
Like this:
@objective (m,Min, sum(LS[i, j]*C[i, j] for i, j ∈ 1:f))
EDIT: Also, you have two loop variables (i, j), but are iterating only over one dimension, that’s the source of the iteration error.
I removed the spaces, thanks.
I’m learning how to code, I don’t know how I can iterate two loop variables.
Learning is great! That’s why I’m here too. Keep asking questions.
