1. A More Malicious Maitre d'

Author

Abstract

In this paper we study the problem of the Malicious Maitre d', as described in Peter Winkler's book Mathematical Puzzles: A Connoisseur's Collection. This problem, attributed to computer scientist Rob Pike, involves seating diners around a circular table with napkins placed between each pair of adjacent settings. The goal of the maitre d' is to seat the diners in a way that maximizes the number of diners who arrive at the table to find the napkins on both the left and right of their place already taken by their neighbors. Winkler proposes a solution to the problem that he claims is optimal. We analyze Winkler's solution using tools from enumerative combinatorics, then present a new strategy that performs better., Comment: 17 pages, 5 figures, 2 tables; to appear in American Mathematical Monthly

Lyons, Sean Nolan, Elfed Lewis Keywords: Autonomous underwater vehicles; Optical fibre sensor; Obstacle avoidance; Behaviour-based control Abstract: This paper describes short range and tactile optical fibre sensors for marine applications. The sensors are designed for obstacle avoidance on unmanned underwater vehicles (UUVs) operating in confined spaces, but have other possible applications. The fibre sensors augment the sensory abilities derived from ultrasonic and other sensors employed for marine proximity measurement. Of particular interest is proximity detection in the 'near' (less than 1m) and tactile areas. The paper describes the basic principle of operation and alternative sensor configurations. Results are given based on laboratory tests and deployment on a mini autonomous submersible in a test pool.
