Dr Altman mentions my software, and points out a couple limitations:
"Ad-hoc definition of compactness"It's true. I saw a bunch of measures of compactness out there, and no consensus on what the best one was, so I made up my own. It has advantages and tradeoffs compared with other measures. If comparing many plans crossed with many measures became a key feature in driving adoption, I'd do it. At some point we're probably going to have a big discussion about what the right measure is.
"Does not permit inclusion of districting criteria other than compactness, population, contiguity."Yup. I'll call that a version-1.0 limitation. It's on my to-do list to consider political-unit contiguity, measuring how many towns and cities and counties get broken by district lines. It may also be a necessary compromise to implement Voting Rights Act 'gerrymandering for good' majority-minory disitricts.

Dr. Altman's talk spends most of its second half recapping and advocating the Public Mapping Project's progress so far and future in making Free/OpenSource web based GIS software for crowd-sourced redistricting. The Open Source world has a long standing maxim that 'many eyes make all bugs shallow', and perhaps that will apply also to the bug of gerrymandering.
