The choice of how to represent the search space for a genetic algorithm (GA) is critical to the GA’s performance. Representations are usually engineered by hand and fixed for the duration of the GA ...

The concept of emergence, and several auxiliary ideas, including coarse-graining, effective theory, and compression, play a huge role in complexity science. Formalizing emergence is becoming more ...

Our campus is closed to the public for this event. When the species composition in a given environment is strongly perturbed by extinctions and invasions, the system may have multiple possible ...

Ghosh, P.,Mitchell, M.,Gold, J. A novel technique is presented to combine genetic algorithms (GAs) with level-set functions to segment objects with known shapes and variabilities on images. The ...

Hernandez-Suarez, C. M.,Castillo-Chavez, C.,Lopez, O. M.,Hernandez-Cuevas, K. In this work we consider every individual of a population to be a server whose state can be either busy (infected) or idle ...

Recent attempts to understand the origin of social fragmentation are based on spin models which include terms accounting for two social phenomena: homophily -- the tendency for people with similar ...

Sole, R. V.,Valverde, S. Large-scale evolution involves several layers of complexity spanning multiple scales, from genes and organisms to whole ecosystems. In this article, we review several models ...
