We enforce a maximum population deviation of 0.1%.
We use a pseudo-county constraint described below which attempts to mimic the norms in Minnesota of generally preserving county, city, and township boundaries.
No manual pre-processing decisions were necessary.
Simulation Notes
We sample 5,000 districting plans for Minnesota across two independent runs of the SMC algorithm.
We use a pseudo-county constraint to limit the county and municipality (i.e., city and township) splits.
Municipality lines are used in Anoka County, Dakota County, Hennepin County, and Ramsey County, which are all counties with populations larger than 40% the target population for a district.
Redistricting requirements
In Minnesota, districts must:
Furthermore, the following principles guide redistricting in Minnesota which stipulate that districts must:
