+
+sisyphus is a piece of software I wrote the context of my graduate automation
+project. My class was taking part in the IEEE ICRA 2012 Virtual Manufacturing
+Automation Competition and part of the competition, was to efficiently stack
+boxes of different sizes on a pallet.
+
+As the knapsack problem is NP hard, sisyphus implements hybrid between
+heuristic and bruteforce approach.
+
+The heuristic is, to group articles of same height into layers, and then stack
+those layers on top of each other.
+
+Different techniques to form layers and different orderings of stacking them
+are then tried out in a bruteforce manner.
