Is it possible to look up values in an array or a dict using integer variables?
@variable(model, x, Int) # restrict x to appropriate values @constraint(model, my_array[x] <= 5)
Or should a binary array with a single one be created and summed over to implement the look up? Like:
@variable(model, x[1:n], Bin) @constraint(model, sum(x[i] for i in 1:n) ==1) @constraint(model, sum(x[i]*my_array[i] for i in 1:n) <= 5)
Is this where you use something like MOI.SOS1? Can you use SOS1 on an array of arrays?
