Under some circumstances, a group of individuals may need to negotiate
together as a negotiation team against another party. Unlike bilateral
negotiation between two individuals, this type of negotiations entails to adopt
an intra-team strategy for negotiation teams in order to make team decisions
and accordingly negotiate with the opponent. It is crucial to be able to
negotiate successfully with heterogeneous opponents since opponents'
negotiation strategy and behavior may vary in an open environment. While one
opponent might collaborate and concede over time, another may not be inclined
to concede. This paper analyzes the performance of recently proposed intra-team
strategies for negotiation teams against different categories of opponents:
competitors, matchers, and conceders. Furthermore, it provides an extension of
the negotiation tool Genius for negotiation teams in bilateral settings.
Consequently, this work facilitates research in negotiation teams.Comment: Novel Insights in Agent-based Complex Automated Negotiation, 201
