please note the YANG is still in a prealpha state, that is in a “work in progress” status.

Requirements

Software

• a Java 6 compliant JRE – preferably the Sun’s one
• the R statistical software
• the igraph package for R

Hardware

• a recent CPU, at least a dual-core or multi-thread one
• at least 1Gb RAM
• a wheel mouse (currently required for ergononic reasons)

Install

Windows users

Most windows users should download the yang_win_32bits.jar. Only rare recent versions of Windows require the 64bits release.
To launch YANG, just double-clic the jar (or open a shell and type in java -jar yang_win_32bits.jar).

YANG preferences will be stored into your “My Documents” folders in the “.yang” directory.

Linux users

Download either yang_linux_gtk2_32bits.jar or yang_linux_gtk2_64bits.jar, depending to your distribution. If unsure of your architecture, open a shell and type “uname -a”. If the result contains “x86_64”, your system is built as a 64 bits one. In this case, your java runtime environment should be 64bits as well (type “java -version” in a shell to check this).

Depending to your distribution and parameters, you may run YANG by a double-clic or a right-click (and select “open with / Sun Java”), or open a shell and type: java -jar yang_linux_gtk2_32bits.jar

OSX users

Please ensure that you are running Java 1.6 (OS X is really no so up-to-date regarding java releases). Opening a shell and typing “java -version” may help you.

Apple users simply have to double-click on the downloaded “dmg” file for mounting it as volume, then to double click on “Yang” for launching it.

other users

This program is written in Java; it may be users in other platforms, as long as they support a JRE, Java2D and SWT.

Please let us know if you successfully used YANG in an exotic platform.

Changelog

2011-05-18

• enhanced layout for the welcome page
• added access to the parameters visu from Legend.
• corrected how screenshots of Bayesian networks are done
• interface between samiam and YANG rewritten
• improved the use of gradients for dynamics network visu
• backups now displayed in a human-friendly format
• corrected the “null” display when no project displayed after several runs
• corrected the bring-to-front method which was not effective under OS X nor windows XP (display of SamIam from YANG)
• examples displayed at first start for helping new users to discover the soft
• more human-friendly recent filepathes
• embedded SQLite database yet working for MacOSX and linux (still a pb with Windows XP)
• improved detection of external programs (R, igraph library)
• no more Mac OS X carbon release; focusing on the cocoa versions.
• Mac OS X release of YANG now bundled as a Mac OS X Java bundle
• Mac OS X release of YANG distributed now distributed on a DMG image file.
• improved look & feel for Mac OS X and Windows
• changed the design of the “rules” tab
• corrected an error when updating the size of domains given math formula
• corrected an error when saving parameters with a null domain
• improved safety of parameters save; attempts to save experiments in a best-effort principle by skipping errors.
• added support for ranges in the “math attributes”
• corrected the display of HTML content for OSX (tested with snow leopard)
• started the translation for french; still in a “frenglish” state

2011-05-12

• added a random component in the selection of agents for attributes rules (avoids artificial regularities that may biases in generated graphs)
• added automatic detection of low framerate; a switch to relevant “low quality” settings is proactively proposed to users in this case
• reduced the verbosity of the program (prevents the display of many prefuse warns)
• disable tabs (ergonomy: users were a bit confused about these tabs that were not usable but looked enabled)
• removed errors that appear when creating networks with empty parameters (index error)
• enhanced propagation of userparameter events (independant thread)
• corrected how display parameters are populated/updated when userparameters are changed (especially linktypes and attributes)
• secured most concurrent calls to parameters which were due to indirect loops in events managements and/or data access (e.g. linktypes)
• removed a bug when loading another project (parameters losts, because of the asynchronicity of parameters save)
• reduce CPU use for dynamic display: layout stopped when the window is hidden, iconified and so on
• removed an error during task EXPORT_NETWORK_AS_MAILLARDTHIRIOT

2011-02-12

• corrected the creation of attributes rules (priorisation of the nodes having the most links not created)s
• added the “reset examples” feature
• corrected default parameters for embedded examples
• added examples: work market, water and farmers, random network

2011-01-21

• design of the welcome page

2011-01-20

• corrected a bug in the management of the probability of link creation by transitivity.
• added the exportation of an experiment as Zip file
• added the possibility to open a Zip file
• enabled the use of “open, create, open from a zip” from the main menu
• corrected a bug in backups management
• moved backups into a specific menu and window
• added the possibity to create a backup point manually

2011-01-13

• corrected the cancellation behaviour of linktype creation
• changed layout in tab “attributes”
• removed the “do you want to save ?” box displayed when nothing loaded (and added the “cancel” button there)
• corrected the bug in the “parameters check” tab (layout pb for windows) and improved this layout
• corrected a layout bug into the “generation rules” tab (pb in windows)
• corrected a bug in tooltips displays

2011-01-12

• project name displayed as the window title
• corrected the coloration of nodes when attributes are numerical
• improved the synchronicity of visualization parameters (SWT and other threads)
• corrected a recent bug in the edition of variables for rules (added variables were put into agents attributes instead of being added to the rule)
• corrected warn message for large CPT for math autoattributes

2011-01-11

• beautiful layout for the parameters panes (especially for dynamic network visualization)
• corrected colors for network visualization
• packaged a first example (social networks in Kenya)
• changed the place were backups are saved (now in a subdirectory of the experiment folder)
• added the possibility to capture views of the network
• exportation of stats in now implemented (kind of a CSV format, that may be opened with OpenOffice, Excel, gnuplot, R…)
• added the possibility to deactivate generations rules
• added edition functionalities for adding and changing link types
• implemented the math parser for automatic generation of large conditional probability tables
• improved efficiency of network vizualisation (labels hidden when zoomed out)
• corrected errors on generation statistics computation
• corrected bugs in the creation of new projects and load of projects
• corrected bugs in the renaming of generation rules (constistency with AutoAttributes) – a bug remains here
