The dataset for other size of VRP instances

[JackeyMiao]

Hi, @wouterkool !

It's a really nice job, and thanks for your sharing!

I've met some problems in my recent works, I try to solve the CVRP problems with neural networks.

However, the lack of dataset brought a lot of troubles to me.

I really need the instances of node size:10,20,50, but my hardware condition is so poor that generating by myself is too time-consuming.

I wonder that if you can share the instances and corresponding resluts of node size:10,20,50 for VRP problems?

It will be so helpful to me,and thank you for your great job again!
