How to set the mix ratio of different goods type in or tools routing solver?

[周卫东]

As the title, I want to add a constraint for the goods {A, B} in the vehicle :

A / B <= 0.4，即 2B >= 5A

Try just setting a constraint like that at every node. 

You’ll have to make sure the ratio is an integer, so multiply by 100 or something, and you’ll probably also find performance might degrade as candidate solutions that do not respect the ratio will be discarded.
