Lemming: A Tool for Guided Plan Selection using Landmarks

Lemming is a visualization tool for the selection of plans for a given problem, allowing the user to efficiently whittle down the set of plans and select their plan(s) of choice. We propose three different user experiences for this process, all based on the principle that using landmarks as guidance can help cut down the set of choice points for the user. The live demonstration at the conference will allow the audience to interact with the tool on different domains and problems.
