I'm trying to use the framework Pyomo in order to solve an VRP with stochastic demands. I was wondering if there is some simple examples of VRP in order to get a start point to solve it.
Any help is welcomed!
Thanks a lot in advance!
Though my answer is late, it's better late than none.
Please visit my github page link! and download the example you want.
It's similar to the ReferenceModel.py link sent earlier but that was written seven years ago and there has not been a modification to it. So I have modified it to run with the current version of pyomo.
Hope you will find it helpful

I am new to Pao.
I am just wondering if anyone can tell me how Pao solves a bi-level problem. Does it transfer to a single-level problem? If it is what kind of algorithm, is KKT? I just need simple answers for the project that I have to finish very soon, unfortunately.
Any help will be appreciated.
Thanks,
Reading some documents and research papers. Try some Github codes. However, I am confused and couldn't have any comprehensive results.
I want to make a scientific calculator for calculating derivatives.
I want to show the steps of the solution.
I have tried to get some API that provides me with the steps of solving the Derivative Questions but have not succeeded.
I found an Api to solve the calculus questions, but it is not giving a proper response on my end.
May it work for you.
I have been trying to improve my application by incorporating updates. However, the current documentation is very confusing on for example how updates would be structure for a chat or a channel.
Any advice on this topic would be much appreciated. Thank you in advance!
Things have changed a lot, but the official Telethon documentation probably explains them good enough now.
You can also view single-file Telethon examples or real world Telethon projects. Maybe I'm a bit late for the answer but hopefully helps other people :)
Hello to the nice Stackoverflow community!
I have difficulties understanding the difference between the Merkle–Damgård construction and the sponge-function used in KECCAK.
The Merkle–Damgård Construction takes in the message-blocks iteratively, but as of what I've found in descriptions, doesn't a sponge function do the same? Illustrations of both look quite similar and I just don't find an explanation I really understand.
Can someone explain the difference somewhat easier?
So I expanded my search for sources using youtube videos. If someone has the same question, I think it is very well explained in this Video:

The explanation starts at minute 18. Hope this helps someone.
Have a nice day!
I am new to this thing and want to use Opta Planner in my project to Solve Vehicle Routing Problem. Can anyone guide me step by step how to use it, it would be great.
Thanks
In the current version (7.7) the docs have a quick start that explains the concepts on another use case and then see the VRP implementation example.
For a future version, we intend to make implementing/modeling VRP even simpler by supporting a Vehicle.visitList style model.
