We consider games in which players search for a hidden prize, and they have asymmetric information about the prize's location. study social payoff equilibria of these games. present sufficient conditions existence an equilibrium that yields first-best (i.e., highest under any strategy profile), we characterize payoff. The results interesting implications innovation contests R&D races.

The National DNA Database (NDNAD) of England and Wales was established on April 10th 1995. The NDNAD is governed by a variety of legislative instruments that mean that DNA samples can be taken if an individual is arrested and detained in a police station. The biological samples and the DNA profiles derived from them can be used for purposes related to the prevention and detection of crime, the ...

OBJECTIVE To report familial occurrence of polyneuropathy associated with monoclonal gammopathy. DESIGN Case reports. PATIENTS We describe 6 patients (3 pairs) with a polyneuropathy associated with IgM monoclonal gammopathy. Four of the 6 patients had a demyelinating polyneuropathy on neurophysiological examination. Three patients had elevated antibodies against myelin-associated glycoprote...

Meta-heuristics have already received considerable attention in various fields of engineering optimization problems. Each of them employes some key features best suited for a specific class of problems due to its type of search space and constraints. The present work develops a Pseudo-random Directional Search, PDS, for adaptive combination of such heuristic operators. It utilizes a short term...
