Stochastic Modeling and Optimization of Phage Display

Levitan, Bennett - Santa Fe Institute - 1997

Phage display, SELEX and other methods of combinatorial chemistry have become very popular means of finding ligands with high affinities to given targets. Despite their success, they suffer from numerous sources of error and bias, such as very low initial concentrations of species, non-specific...

Optimizing Epochal Evolutionary Search: Population-Size Dependent Theory

Nimwegen, Erik van; Crutchfield, James P. - Santa Fe Institute - 1998

Technological change at the firm level has commonly been modeled as random sampling from a fixed distribution o f possibilities. Such models, however, typically ignore empirically important aspects of the firm's search process, notably the observation that the present state of the firm guides...

Pattern Formation and Optimization in Army Ant Raids

Solé, Ricard V.; Bonabeau, Eric; Delgado, Jordi; … - Santa Fe Institute - 1999

Army ant colonies display complex foraging raid patterns involving thousands of individuals communicating through chemical trails. In this paper we explore, by means of a simple search algorithm, the properties of these trails in order to test the hypothesis that their structure reflects an...
