[new paper] “Political districting to maximize whole counties” coauthored with Maral Shahmizad

https://github.com/maralshahmizad/Political-Districting-to-Maximize-Whole-Counties/blob/main/political-districting-to-maximize-whole-counties.pdf

We propose a combinatorial Benders decomposition algorithm, solving (nearly) all instances across the USA.

Our approach provides intuitive optimality proofs suitable for courts/laypeople: at least one county must be split in each enclosed region. #orms

Jury simulation using SimPy

In this article we design and build a SimPy simulation model of a jury summoning process The goal is to reduce the number of people summoned for jury service.

Simulation is often seen as an easy way to model to situation. It is not. This model highlights a key lesson for simulation modelling in general: details matter, sometimes a lot.

Efficient jury empanelling: Respecting people's time

This article is inspired by a recent experience of being summoned for jury service. We describe a simulation model of the jury selection process. The goal is to explore how the needs of the justice system can be met while also respecting the time of people who report for jury service. Specifically, we want to see if the number of people summoned can be reduced while ensuring that sufficient people are available for the scheduled trials.

Jury service is an important civic duty, providing a way for people to directly participate in upholding the law and contribute to their community. But the jury service process, like much of the justice system, is designed around the needs of the system rather than the needs of the people it serves.
