Detailed Description

--— KnapsackSearchNode --— KnapsackSearchNode is a class used to describe a decision in the decision search tree.

The node is defined by a pointer to the parent search node and an assignment (see KnapsackAssignement). As the current state is not explicitly stored in a search node, one should go through the search tree to incrementally build a partial solution from a previous search node.
