Introducing Spacial Graphs ( updated
We introduce spatial graphs through a natural extension of the concept of pla-narity in three dimensions. For a graph G=(V,E), a face is a simple cycle of edges, and a complete set of faces is such that each edge belonging to a cycle in E is on at least one face in the set. G is spatial if admits a three-dimensional representation R with a complete set of faces consisting of simple surfaces, su...
متن کاملOn Optimal Strategies for a Hat Game on Graphs
The following problem was introduced by Marcin Krzywkowski as a generalization of a problem of Todd Ebert. After initially coordinating a strategy, n players each occupies a different vertex of a graph. Either blue or red hats are placed randomly and independently on their heads. Each player sees the colors of the hats of players in neighboring vertices and no other hats (and hence, in particul...
متن کاملThe Three Colour Hat Guessing Game on Cycle Graphs
We study a cooperative game in which each member of a team of N players, wearing coloured hats and situated at the vertices of the cycle graph CN , is guessing their own hat colour merely on the basis of observing the hats worn by their two neighbours without exchanging the information. Each hat can have one of three colours. A predetermined guessing strategy is winning if it guarantees at leas...
متن کاملWer die Wahl hat, hat die Qual
Deutschland steht 2009 vor einem überaus schwierigen Jahr. Vorausschauende Manager schielen aber weniger auf die nicht beeinflussbaren Eckdaten, sondern finden heraus, welche Verbesserungspotenziale in ihrer Firma schlummern. Eine Alternative zu Cost-Cutting-Programmen kann die Optimierung des Projektmanagements sein. Ein kritischer Blick auf den Markt der dafür erforderlichen Projektmanagement...
