Hello,
I'm trying to do the following:
@defConstraint(m, t == sum{param[i,j]*x[i,j], (i,j)=con_values}
When I test it in the interpreter I get:
*ERROR: no method
addToExpression(GenericAffExpr{Float64,Variable},Float64,Array{Int64,1})*
with con_values defined as [(1,2), (3,4)] and x defined as:
for (i,j)=con_values
@defVar(m, x[i,j] >=0)
end
The docs show using the sum operator with single single value arrays. From
the code illustrating what sum does it seems like it shouldn't be a stretch
to do what I have above; I even use the list of tuples in the for loop to
define the variables.
How can I achieve a constraint definition as I have it above?
