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'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 have an exam coming up, and I need to learn a bit more about IDEs (Integretated Development Error).
I have already looked on Wikipedia, and used the Simple English feature, but I haven't really been helped by it, which is why I am here.
If you have any tips I'd appreciate it, because my exam is in 3 weeks. Thanks in advance!
Edit: I also need help on hexadecimal, which I have also seen on Wikipedia, again not being helpful.
Can someone please help me understanding which one is more efficient strstr() or KMP as recently I was doing a question on SPOJ and found that strstr() was in one way or other faster than KMP..
someone please explain the mystery behind this..
You are comparing apples with pears, strstr() is a function to find substrings, KMP is an algorithm to do it, so strstr() could theoretically be implemented using KMP. You need to find out which algorithm is the strstr() in question implementing to give a statement.
Take a look at this answer and the comments on it.
I'm using Microsoft solver, and have wanted to ask how can i find
K-best solutions using LP and not just the optimal one?
I know that CPLEX has solution pool feature for
example.
Thank you for the help.
Paul.
There is a nice blog post by Paul Rubin about finding k best solutions.
this question might look dumb but I need to have a clear idea when learning about something new :)
In SSADM, do we have to do a comprehensive study about the "feasibility" (Stage0)? How can we get an idea about the feasibility before even performing "investigation" (Stage1) about the business?
What is actually expected in Stage0 anyway?
Thanks. Hope someone would shed a light on this.
My references are not available to me at the moment so this is from memory - I think the feasibility stage is about getting the project off the ground - why should people commit resources to even an investigation. So when they are talking about feasibility, and the contents of the report things that are likely to be covered are a broad statement of the problem; why it is a problem; why a system solution looks like the way to go to solve the problem; who will pay for it; who is sponsering it and who will benefit from it.
By definition, it is impossible to do a comprehensive study of feasibility before getting into the work, but rather I think of a feasibility picture as painting a picture of what might be if this project were to go ahead - so broad stroke rather than detailed and comprehensive.
In essence the feasibility stage is answering the questions "why should we bother with this project; and if we are bothered to do this project do we think we are capable of doing it.
