SimMode is where the election happens and handles the processing of inputs geometries, options, and changes to output data structures.

SimMode

SimMode has the following states: SimModeOne and SimModeSample. Each state is like a different game.

• SimModeOne does one election sequence and gets one result: {sequenceResults}
• SimModeSample does a sampling of many elections to get a distribution of results: {samplingResults}

Here’s a synopsis of both SimModeOne and SimModeSample:

• Call update() method of the mode to get output.
• The Sim checks if there are any changes and that controls the flow. If there are no changes, then there is no output.
• Any election options that depend on other options are updated.
• Districts are updated if they need to be.
• The geometry of the problem is assembled into a data structure.
• For SimModeOne, an election sequence is run on the geometry to generate output data structures.
• For SimModeSample, an ElectionSampler is run, which then calls election sequence multiple times.
• These data structures are passed to View. Specifically, SimMode passes its results to ViewMode’s update method to visualize results.
