+# Packing
+
+This folder contains utilities and solvers for several packing problems:
+knapsack and bin packing, including generalizations. The solvers take as input a
+problem description in ProtoBuf.
+
+## Knapsack
+
+A typical knapsack problem considers a single container (the knapsack) and many
+items. The container has a maximum capacity, items have both a weight and a
+value. The goal is to find the subset of items that respects the capacity
+constraint and has the maximum value. There can be only one container. More
+generally, the knapsack problem models resource allocation.
