atoptima / colunademos.jl Goto Github PK

Hello,

I'm implementing the dial-a-ride problem using pricing callbacks to generate a new entering column in the master problem and I'm referring to your work of CapacitatedVehicleRouting demo:https://github.com/atoptima/ColunaDemos.jl/tree/master/src/CapacitatedVehicleRouting

I'm confused about:

1. how to make the master problem and subproblem being iteratively solved using callback?
2. should I feed the model.jl with the initial solution?
3. from model.jl, I can only get the defined cvrp model, x (variables), and decomposed model, how can I use the code to obtain the results? I'm quite confused about the whole process...

the status of my packages:
Gurobi v.0.8.1
JuMP v.0.21.4
MathOptInterface v0.9.20
BlockDecomposition v1.2.5

Thank you in advance!

Best,
Yue
