    The extremal dynamics of the Bak-Sneppen model can be converted into an optimization algorithm called extremal optimization. Attractive features of the model include the following: it is straightforward to relate the sum of all fitnesses to the cost function of the system; in the self-organized critical state to which the system inevitably evolves, almost all species have a much better than random...

    Scientists and engineers often need to compute mathematical functions that depend in a complicated way on their parameters. Such functions-especially those whose analytical properties researchers have studied extensively-are called transcendental functions or special functions. There are three important reasons for visualizing such functions: to better understand their analytical properties, to cl... View full abstract»

    Computing systems inspired by biological systems (biocomputation) are one possible alternative currently being investigated. Whether it will impact information technology as defined today is still unclear. The field of biocomputation has a twofold definition: the use of biology or biological processes as metaphor, inspiration, or enabler in developing new computing technologies and new areas of co...

Aims & Scope

The computational and data-centric problems faced by scientists and engineers transcend disciplines. There is a need to share knowledge of algorithms, software, and architectures, and to transmit lessons-learned to a broad scientific audience. Computing in Science & Engineering (CiSE) is a cross-disciplinary, international publication that meets this need by presenting contributions of high interest and educational value from a variety of fields, including—but not limited to—physics, biology, chemistry, and astronomy. CiSE emphasizes innovative applications in advanced computing, simulation, and analytics, among other cutting-edge techniques. CiSE publishes peer-reviewed research articles, and also runs departments spanning news and analyses, topical reviews, tutorials, case studies, and more.
