Computer simulated evolution of virtual creatures (1994)

"This narrated computer animation shows results from a research project involving simulated Darwinian evolutions of virtual block creatures. A population of several hundred creatures is created within a supercomputer, and each creature is tested for their ability to perform a given task, such the ability to swim in a simulated water environment. The successful survive, and their virtual genes containing coded instructions for their growth, are copied, combined, and mutated to make offspring for a new population. The new creatures are again tested, and some may be improvements on their parents. As this cycle of variation and selection continues, creatures with more and more successful behaviors can emerge.

The creatures shown are results the final products from many independent simulations in which they were selected for swimming, walking, jumping, following, and competing for control of a green cube."

Open Archives Initiative

"The Open Archives Initiative develops and promotes interoperability standards that aim to facilitate the efficient dissemination of content. The Open Archives Initiative has its roots in an effort to enhance access to e–print archives as a means of increasing the availability of scholarly communication. Continued support of this work remains a cornerstone of the Open Archives program. The fundamental technological framework and standards that are developing to support this work are, however, independent of the both the type of content offered and the economic mechanisms surrounding that content, and promise to have much broader relevance in opening up access to a range of digital materials. As a result, the Open Archives Initiative is currently an organization and an effort explicitly in transition, and is committed to exploring and enabling this new and broader range of applications. As we gain greater knowledge of the scope of applicability of the underlying technology and standards being developed, and begin to understand the structure and culture of the various adopter communities, we expect that we will have to make continued evolutionary changes to both the mission and organization of the Open Archives Initiative.

The OAI–ORE Executive provides overall leadership to the project and holds primary responsibility for the project budget and the ultimate success of the work. Carl Lagoze – Computing and Information Science, Cornell University, Herbert Van de Sompel – Digital Library Research and Prototyping, Los Alamos National Laboratory Research Library.

Funding and Support: Support for Open Archives Initiative activities has come from the Andrew W. Mellon Foundation, the Coalition for Networked Information, the Digital Library Federation, and from the National Science Foundation (IIS–9817416 and IIS–0430906)."
