"oreas makes the scientific knowledge in the area of optimization available for industrial applications. While scientific progress in business informatics is quickly applied in practice, the exploitation of scientific knowledge in optimization algorithm design that flourishes in Computer Science and Applied Mathematics is still in its infancy, yet provides enormous potential. oreas bridges the gap not by expecting its clients to understand the theory but by studying their needs and develop solutions in their language, with latest technology working behind the scenes for their profit."

Founded in 1999, oreas develops innovative software solutions for the automatic layout of diagrams that visualize relationships between objects. Such diagrams, also called graphs in mathematics, occur in various forms in practice:
  • computer networks, social networks
  • business processes
  • database schemas
  • software systems (e.g., UML class diagrams)
  • organization diagrams
  • data-flow diagrams

With the GoVisual libraries product line, oreas offers their customers state-of-the-art diagram layout technology for integration into their own applications. The layout methods provided range from established, reasonably priced standard techniques to unique specialized algorithms like, e.g., for the automatic layout of UML class diagrams. A wide range of supported platforms (C++, .NET, COM, Java) and intuitive interfaces ensure an easy integration of the library.

The oreas team guarantees the high quality of GoVisual layout algorithms. Prof. Dr. Michael Jünger (partner) and Prof. Dr. Petra Mutzel (partner) are among the leading researchers in the field of graph drawing and operations research for many years. In October 2000, Prof. Mutzel received the Alcatel SEL Research Award Technical Communication for her work in the field of graph drawing. Today, she holds the chair for Algorithm Engineering at the University of Dortmund. The foundation of the commercial software was laid at the research center caesar in Bonn, where the oreas team constituted the project group Graph Drawing. Currently, scientific research is performed by the groups of Prof. Mutzel at the University of Dortmund and Prof. Jünger at the University of Cologne. caesar building

Graph drawing problems arising in practice rarely satisfy the assumptions made by standard methods. In many cases, there are further requirements the created layout must meet. The superior scientific and technical expertise of its team enables oreas to develop tailor-made software solutions that fit the particular needs of a customer.
