Cooperative agent systems are designed so that each is working
toward the same common good. The problem is that software systems
are complex and can be subverted by an adversary to either break
the system or potentially worse, create sneaky agents who are
willing to cooperate when the stakes are low and take selfish,
greedy actions when the rewards rise. This research focuses on the
ability of a group of agents to reason about the trustworthiness of
each other and make optimal decisions about whether to cooperate. A
TI-POMDP is developed to model the trust interactions between
agents, enabling the agents to select the best course of action
from the current state. The TI-POMDP is a novel approach to
multiagent cooperation based on an I-POMDP augmented with trust
relationships. Experiments demonstrate the TI-POMDP's ability to
accurately track the trust levels of agents with hidden agendas,
providing the agents the information needed to make decisions based
on their level of trust and model of the environment. On average,
agents achieved rewards 3.8 times higher using the TI-POMDP model
compared to a trust vector model.
