Does iRedistrict support starting from an existing plan

Yes, with iRedistrict, you can load an existing plan as a boundary, then ask the software to produce plans minimizing the cross of this boundary. It supports working with multiple boundaries. That menas, you can minimize the cross of an exiting plan and also administrative boundaries.


How can iRedistrict produce 0-deviation plan?

One solution is to set higher weight and very low threshold on population equality before running the optimization. After producing the plans, lock the districts that have 0-deviation and rerun the redistricting optimization. Repeat it several times, you will get 0-deviation plans. Another solution is to fine tune the plan boundaries. Pick a plan and mix it with the block layer to produce a polygon file that has blocks around the plan boundaries. Then run redistricting optimization on this file. Repeat the first solution if necessary.
