GAPs: Geospatial Abduction Problems
Paulo Shakarian, V. S. Subrahmanian, Maria Luisa Sapino
Article No.: 7
DOI: 10.1145/2036264.2036271

There are many applications where we observe various phenomena in space (e.g., locations of victims of a serial killer), and where we want to infer “partner” locations (e.g., the location where the killer lives) that are geospatially...

An Adaptive Agent for Negotiating with People in Different Cultures
Ya’akov Gal, Sarit Kraus, Michele Gelfand, Hilal Khashan, Elizabeth Salmon
Article No.: 8
DOI: 10.1145/2036264.2036272

The rapid dissemination of technology such as the Internet across geographical and ethnic lines is opening up opportunities for computer agents to negotiate with people of diverse cultural and organizational affiliations. To negotiate proficiently...

Fair Seeding in Knockout Tournaments
Thuc Vu, Yoav Shoham
Article No.: 9
DOI: 10.1145/2036264.2036273

We investigated the existence of fair seeding in knockout tournaments. We define two fairness criteria, both adapted from the literature: envy-freeness and order preservation. We show how to achieve the first criterion in tournaments whose...
