I have an optimization problem and I'm using Python and Gurobi to optimize it. In my problem formulation there is a constraint that has a nested sum.
constraint
I've recently started learning python and I searched in gurobi documentation and example codes and I couldn't find any example of nested sum.
I was wondering if anyone could help me solve this problem. Thanks in advance!
Use two for statements inside the quicksum()
function and two for statements in the generator expression:
mycts = m.addConstrs((quicksum(x[i,f,p]*y[i,f,p,t]
for i in I for p in P[i,f]) <= z[f,t]
for f in F for t in T), "myconstraint")
where m is your Model
object.
