In ecosystems, for example, niches act as semi-permeable boundaries, and smells and visual patterns serve as signals; governments have departmental hierarchies with memoranda acting as signals; and so it is with other cas. Despite a wealth of data and descriptions concerning different cas, there remain many unanswered questions about "steering" these systems. In Signals and Boundaries, John Holland argues that understanding the origin of the intricate signal/border hierarchies of these systems is the key to answering such questions. He develops an overarching framework for comparing and steering cas through the mechanisms that generate their signal/boundary hierarchies. Holland lays out a path for developing the framework that emphasizes agents, niches, theory, and mathematical models. He discusses, among other topics, theory construction; signal-processing agents; networks as representations of signal/boundary interaction; adaptation; recombination and reproduction; the use of tagged urn models (adapted from elementary probability theory) to represent boundary hierarchies; finitely generated systems as a way to tie the models examined into a single framework; the framework itself, illustrated by a simple finitely generated version of the development of a multi-celled organism; and Markov processes. 606 $aAdaptive control systems 606 $aAdaptation (Biology)$xMathematical models 606 $aSignals and signaling$xMathematical models 610 $aCOGNITIVE SCIENCES/General 610 $aCOMPUTER SCIENCE/General 615 0$aAdaptive control systems. 615 0$aAdaptation (Biology)$xMathematical models. 615 0$aSignals and signaling$xMathematical models. 676 $a003 700 $aHolland$b John H$g(John Henry),$f1929-2015.$028441 801 0$bOCoLC-P 801 1$bOCoLC-P 906 $aBOOK 912 $a9910779222103321 996 $aSignals and boundaries$91079223 997 $aUNINA
