TALplanner in IPC-2002: Extensions and Control Rules
TALplanner is a forward-chaining planner that relies on domain knowledge in
the shape of temporal logic formulas in order to prune irrelevant parts of the
search space. TALplanner recently participated in the third International
Planning Competition, which had a clear emphasis on increasing the complexity
of the problem domains being used as benchmark tests and the expressivity
required to represent these domains in a planning system. Like many other
planners, TALplanner had support for some but not all aspects of this increase
in expressivity, and a number of changes to the planner were required. After a
short introduction to TALplanner, this article describes some of the changes
that were made before and during the competition. We also describe the process
of introducing suitable domain knowledge for several of the competition
domains
Algorithmic Jim Crow
This Article contends that current immigration- and security-related vetting protocols risk promulgating an algorithmically driven form of Jim Crow. Under the “separate but equal” discrimination of a historic Jim Crow regime, state laws required mandatory separation and discrimination on the front end, while purportedly establishing equality on the back end. In contrast, an Algorithmic Jim Crow regime allows for “equal but separate” discrimination. Under Algorithmic Jim Crow, equal vetting and database screening of all citizens and noncitizens will make it appear that fairness and equality principles are preserved on the front end. Algorithmic Jim Crow, however, will enable discrimination on the back end in the form of designing, interpreting, and acting upon vetting and screening systems in ways that result in a disparate impact
