On Hats and other Covers
We study a game puzzle that has enjoyed recent popularity among mathematicians, computer scientist, coding theorists and even the mass press. In the game, n players are fitted with randomly assigned colored hats. Individual players can see their teammates’ hat colors, but not their own. Based on this information, and without any further communication, each player must attempt to guess his hat c...

techniques attempt to differentiate between stego-objects and cover-objects. In recent work we developed an analytic upper bound for the steganographic capacity of LSB based steganographic techniques for a given false of detection. In this paper we look at adaptive steganographic techniques. Adaptive steganographic techniques steps to escape detection. We explore different techniques that can b...
متن کاملCovering Codes for Hats-on-a-line
We consider a popular game puzzle, called Hats-on-a-line, wherein a warden has n prisoners, each one wearing a randomly assigned black or white hat, stand in a line. Thus each prisoner can see the colors of all hats before him, but not his or of those behind him. Everyone can hear the answer called out by each prisoner. Based on this information and without any further communication, each priso...
متن کاملHats, auctions and derandomization
We investigate derandomizations of digital good randomized auctions. We propose a general derandomization method which can be used to show that for every random auction there exists a deterministic auction having asymptotically the same revenue. In addition, we construct an explicit optimal deterministic auction for bi-valued auctions.
متن کاملProgram Transformation Using HATS 1.84
This article gives an overview of a transformation system called HATS – a freely available platform independent IDE facilitating experimentation in transformation-oriented software development. Examples are discussed highlighting how the transformational abstractions provided by HATS can be used to solve various problems.
