Two algorithms for the package-exchange robot-routing problem
We present and analyze two new algorithms for the package-exchange robot-routing problem (PERR): restriction to inidividual paths (RIP) and bubbletree. RIP provably produces a makespan that is O(SIC+k^2), where SIC is the sum of the lengths of the individual paths and k is the number of robots. Bubbletree produces a makespan that is O(n), where n is the number of nodes. With optimizations bubbletree can also achieve a makespan of O((k+l)logk), where l is the longest path from start to goal in the bubbletree subgraph.
