The Robinson-Foulds (RF) metric is the measure most widely used in comparing phylogenetic trees; it can be computed in linear time using Day's algorithm. When faced with the need to compare large numbers of large trees, however, even linear time becomes prohibitive. We present a randomized approximation scheme that provides, in sublinear time and with high(More)
Sandia's Umbra modular simulation framework was designed to enable the modeling of robots for manufacturing, military, and security system concept evaluation. Umbra generalizes data-flow-based simulation to enable modeling of heterogeneous interaction phenomena via a <i>multiple worlds</i> abstraction. This and other features make Umbra particularly(More)
