Given a double round-robin tournament, the Traveling Umpire Problem (TUP) seeks to assign umpires to the games of the tournament while minimizing the total distance traveled by the umpires. The assignment must satisfy constraints that prevent umpires from seeing teams and venues too often, while making sure all games have umpires in every round, and all umpires visit all venues. We propose a ne...

Kriegspiel is a variant of the game of Chess, introduced to make it more similar to wargames. It mainly differs from Chess in that players can only see their own pieces: they have to refer to a neutral agent – the umpire, or referee – to acquire additional, but always incomplete, information. This paper deals with the development of a visual interface to play Kriegspiel over the Internet Chess ...

It can be dangerous, played with a hard ball flying at great velocities, and accidents have occasionally been fatal. Traditionally, cricket has been played during the day, using a dark red ball. Since the late 1970s, a shorter form of one-day cricket has been played both during the day and at night un...

During these competitions, programming tools play a vital role. Due to popularity of areas, large number research about scheduling related done many researchers devoted themselves this yield. However, there still problems be solved, models room for improveme...

The Traveling Umpire Problem (TUP) is an optimization problem in which umpires have to be assigned to games in a double round robin tournament. The objective is to obtain a solution with minimum total travel distance over all umpires, while respecting hard constraints on assignments and sequences. Up till now, no general nor dedicated algorithm was able to solve all instances with 12 and 14 tea...

This paper describes a method for representing and/or recognizing human motion using an eigenspace analysis, referred to a tuned eigenspace, that is responsible for storing various human motions in terms of their sequential postures in an eigenspace and for recognizing unfamiliar posture and/or motion from the tuned eigenspace. We have also analyzed human dress texture problem, caused by wearin...

But so far in 2010, he has struggled with his control, necessitating a stint with th...

Previous studies have shown that sport officials’ decisions can be impacted by biases associated with expectations. The aim of this study was to determine whether elite cricket umpires’ are also influenced expectations batter skill. LBW (n = 5578) from actual level matches in Australia between 2009 and 2016 were analysed a multi-level binomial logistic regression paradigm. In our first model, w...
