Situations that present individuals with a conflict between local and global gains often result in a behavioral pattern known as melioration — a preference for immediate rewards over higher long-term gains. Using a variant of a paradigm by Tunney & Shanks (2002), we explored the potential role of feedback as a means to reduce this bias. We hypothesized that frequent and informative feedback abo...

We study the fundamental problem of how devices, operating over a wireless medium, can discover potential communication partners. For the devices, the spectrum is divided into m frequency channels. As multiple devices share these channels, they have to cope with collisions while they are trying to find other devices in the system. Moreover, we assume an adversarial jammer to block some of the a...
