Hello, I’m a beginner with julia and working on a MIP optimization problem and I’ve been having trouble finishing my objective. Below is the portion of the objective I have traced the error to. sum(sum(3*t[i,j,l]+v1[i,j,l] for l in 1:days)*from_site_dist[i,j] for i in 1:sites for j in 1:stores) T…

According to your line of code I tried the following MWE (minimal working example, see also here: https://discourse.julialang.org/t/psa-make-it-easier-to-help-you ) julia> days=7 julia> sites=5 julia> stores=12 julia> t=rand(Int,sites,stores,days); julia> v1=rand(Int,sites,stores,days); julia> from_…

You can check for your arrays, the following should all give true: julia> size(t)[3]==size(v1)[3]==days true julia> size(t)[2]==size(v1)[2]==size(from_site_dist)[2]==stores true julia> size(t)[1]==size(v1)[1]==size(from_site_dist)[1]==sites true

Should have used this MWE strategy from the start, I’ll make sure to start implementing it in my debugging. This helped me fix the issue, thanks.
