Simple Compromise Strategies in Multivariate Stratification

Compromise strategies for action selection.

Among the many properties suggested for action-selection mechanisms, a prominent one is the ability to select compromise actions, i.e. actions that are not the best to satisfy any active goal in isolation, but rather compromise between multiple goals. This paper briefly reviews the history of compromise behaviour and presents experimental analyses of it in an attempt to determine how much compr...

Compromise Strategies for Constraint Agents

We describe several joint problem solving strategies for a team of multi-interest constraint-based reasoning agents. Agents y/eld in one area of conflict in order to gain concessions in another area. For example, in a distributed meeting scheduling problem, individuals with different preferences may be willing to give up the choice of the location for the meeting if allowed to choose the time o...

Compromise Strategies for Action Selection: Supplementary Material

The dynamic programming technique used in the paper overlays a grid of points on top of the problem space and calculates the maximum expected utility of each location given optimal future actions. This is done recursively starting at the target locations and moving outward until values for all points are calculated, and then repeating the process until the values converge. Using the equations g...

Stratification by a multivariate confounder score.

The complexity and inefficiency of multiple cross-classification as a means of controlling confounding in etiologic research may be avoided upon summarizing the pattern of confounding factors for each subject in terms of a multivariate score. The control of confounding may be based on stratification by the score, with stratum-specific contingency tables obtained and analyzed in the usual manner.
