A cutting-plane module and tutorial are now included in the app. To run the tutorial, tap the Tutorial button at the top right on the Cutting Planes screen.
1.5
2015-05-18
Animations of perfect matching and spanning tree algorithms. Now you can pause animations and enter a step-by-step mode to see the progress of the solution methods for TSP cutting planes, tour heuristics, spanning trees, Held-Karp 1-trees, and Edmonds' blossom algorithm.
1.4
2014-08-30
Can now compute and display shortest tours on maps, using geometric, walking, or driving distances. New user interface with context-sensitive information/settings pages.
1.3.1
