E42 (WebStart) Application
Version 1.2
(requires java plugin 1.4)
E42 is a simulation tool for creating Boolean Discrete Dynamic Systems consisting of N nodes, each of which has K inputs. For fuller explanations and research results go here. E42 Version 1.2 integrates TAO Tool (see separate tool, below) into the E42 interface. Beta Version 1.2.9 is currently available

| Meta-TAO. Meta-TAO is a tool for exploring higher order relations among changes in changes in Boolean Systems. It is new and under development. Versions are continuously being updated; see corresponding link for details. Once the Meta-TAO Tool is evolved to a reasonabley stable plateau it will be integrated into a future version of E42 WebStart. (requires java plugin 1.4 ) |
| |
| Dynamic Form Analysis Tool This tool is in early development. It is being used to decompose complex patterns humans perceive in certain dyanamic forms. (requires java plugin 1.4 ) |

| Sierpinski Wrapper. This program wraps a Sierpinski Gasket around manifolds of various circumferences. The circumference represents attractor cycle length, L. The user can input L and also input the number of rows, R, in the Sierpinski Gasket. The output is an image of the S-Wrap transform. This shows that the S-Wrap transform produces a form of symmetry that generates the derivatives of attractor cycles on a Boolean Landscape. |
| |
| Basin Converter This tool converts basin numbers created by TAO to Basin numbers that are based on the lowest Boolean value (of the rotated basin). TAO finds basins pseudo-randomly and assigns a number to the basin in the Basin Archive in the order of its discovering the basin. The Basin Converter tool goes through the archive and renumbers the basins with lowest basin number (for any length, L) assigned to the basin that starts with the lowest Boolean value. |
Vector Converter
Converts a RowXColumn table (of 0's and 1's) into and E42 file. For example a RxC table can become a Boolean landscape (as if generated by an eefer) that has R attractors each with only 1 node and each with cycle length, L = C. After this conversion we can input the artificial Boolean landscape into Meta-TAO or into the TAO-Meta-TAO Basin Search Tool. We can also transpose the RxC table so that we get an artificial landscape with R attractors each of L=1. |
| Symmetry Group-Finder-Tool This tools finds symmetry groups based on TAO and Meta-TAO analysis. Related to but different than the TAO-Meta-TAO Search Tool. |
| New Media Executable Creator This tool allows you to save an instance of an E42 eefer as a Windows executable Applet file. |
| TAO-Meta-TAO Attractor Search Tool This tools shows how TAO and/or Meta-TAO can transform a target attractor another attractor or into series of other attractors. This tool starts in one attractor and shows who transforms of that attractor can find other attractors. Related to but different than Symmetry Group Finder Tool. |
OLDER VERSIONS OF E42 |
| The following older versions of E42 save their files in an online archive accessible to all researchers who have internet access. For this reason they are still frequently used. The newer WebStart versions of E42 (abov) save their files locally to the users hard drive or other desired location. We are working on uploading software that will allow researchers using the new versions to share E42 files (which people seem to call either eefers or E4's) in a common archive. Files made in the WebStart versions of and the older versions are not compatible but can be converted. A yet (as of November 8, 2006) unreleased version of E42 will have a file converter built in. |

Discrete Dynamic Systems MODELER v0.9
(requires
java plugin 1.4 )Version 5
E42 is a simulation tool for creating Boolean Discrete Dynamic Systems consisting
of N nodes, each of which has K inputs. For fuller explanations and research
results go here. |
| TAO
Tool: The Flow Change across Time (requires
java plugin 1.4 ) Version 2
TAO is a tool for examining change over
time in a Boolean Dynamic System. It is epistemologically grounded in
the idea that the fundamental process of knowing is detecting differences.

| DISCLAIMERS: *** This
is an active research area. ***Software is being updated on a daily basis
so menu structure, features, etc. change constantly. ***We build with
the latest Java version available, so the latest Java
plugin is required. ***Interfaces are designed to answer specific
research questions and so are not usually intuitive and simple. ***Documentation
is nearly non-existent, and where there is documentation, it lags behind
the constant software changes. ***We are very happy to communicate with
you about these tools and provide you with information that allows you
to use the software to demonstrate many dynamic system phenomena and to
answer your own research questions.
