DESCRIPTION

bugsx runs under MIT’s X11 window system. It was written under UNIX but should be easily portable. It is a program which draws the biomorphs based on parametric plots of Fourier sine and cosine series and let’s you play with them using the genetic algorithm.

The original version which ran under Suntools and XViews was written by Joshua R. Smith sometime 1990. See the ’credits’ section for more details.

For more information about the theoretic backgrounds of bugsx consult Joshua R. Smith’s paper distributed with this program (in postscript format). It can also be gotten from: http://physics.www.media.mit.edu/~jrs/biomorphs.ps

COMMAND LINE PARAMETERS

bugsx accepts the following command line options:

        +rv                     reverse video (use to override xrdb entry)
        +synchronous            syncronous mode (use to override xrdb entry)

BRIEF USER’S GUIDE

Once you have started bugsx you will get a window containing the drawing windows and 3 menus. The Menus are:

        Initialize - Initializes the gene pool
        Breed      - Breed the selected organisms
        Quit       - exits bugsx

Once you have chosen "Initialize" and the first set of drawings is shown, you can select the ones you wish to be included in the cross-breeding by clicking (with the left button) on a drawing window. The selected organisms will be drawn inverse.

Clicking on Breed will cross breed the selected organisms using the genetic algorithm. If you have not selected at least two organisms, a set of at least two will be randomly chosen and used for the breeding.

The following keys can be used to control bugsx:

        q - quit bugsx
        i - initialize population
        b - breed
