[CHiPPS] Questions on ALPS interface

[Hans Pirnay]

Hello everyone,

first of all, thanks for the great piece of code!

While using the ALPS interface I have come across two questions:

1. what is the difference between KnowledgeBroker::getIncumbentValue()
and KnowledgeBroker::getBestQuality() ?

2. what is the integer output of the function AlpsTreeNode::process
that I am supposed to overload supposed to be? In the Knap example,
this returns "false" (e.g. 0) if no solution was found and 1
otherwise. Is that how it's supposed to be done?

Thanks

Hans
