This is the README file for BBBB U U GGGGG SSSSS X X B B U U G S X X BBBB U U G GGG SSSSS X B B U U G G S X X BBBB UUU GGGGG SSSSS X X 1) Author & Copyright bugsx was written by (C) Copyright 1995-1997 Robert Gasch (Robert_Gasch@peoplesoft.com) http://www.peoplesoft.com/peoplepages/g/robert_gasch/index.htm (C) Copyright 1990-1997 Joshua R. Smith (firstname.lastname@example.org) http://physics.www.media.mit.edu/~jrs is copyright by the author(s). I (Robert_Gasch@peoplesoft.com) maintain the X11 port and Joshua maintains any other ports. See section 4 and 17 for more info. 2) Distribution Policy Permission to use, copy, modify and distribute this software for any purpose and without fee is hereby granted, provided that this copyright notice appear in all copies as well as supporting documentation. All work developed as a consequence of the use of this program should duly acknowledge such use. See the GNU General Public Licence for more information. What does this mean? This means that you can pretty much do with it what you want as long as you don't charge substantially more than the distribution costs for it (of course you have to make the source available). This makes software distributions like Walnut Creek or Infomagic perfectly acceptable. It does NOT matter wether you use it at home or in a comercial environment. If you want to include it in a major commercial distribution you need my permission to do so. 3) Guarantees bugsx should work all right *but* No representations are made about the suitability of this software for any purpose. This software is provided "as is" without express or implied warranty. 4) What is bugsx? 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 gzip'ed postscript format as bugs.ps.gz. You have to uncompress this file with 'gunzip' before you can print it. Gunzip should be available at an archive near you. The paper can also be gotten from: http://physics.www.media.mit.edu/~jrs/biomorphs.ps I (Robert_Gasch@peoplesoft.com) maintain the X11 port and Joshua (email@example.com) maintains any other ports. See section 4, and 17 for more info. 5) Version Number The current version number is 1.08 6) Where can I get Bugsx from? Bugsx can be gotten from the following FTP sites: media.mit.edu (/physics/dist/bugs) ftp.x.org (/contrib/applications) 7) What if you change the program? please mail me (Robert_Gasch@peoplesoft.com) the changes(!) as I'd like to act as the central source for bugsx. This will also enable me to include your changes in a future release. If your changes are generic, I'll pass the changes on so that other versions of BUGS can also benefit from your input. 8) Systems currently supported Any resonable UNIX-type system running X11 should be able to compile and run bugsx. I've tested it on the following systems: Linux AIX 9) How do I get started? This section assumes that you have all the necessary files. (The file "Manifest" contains a list of distributed files.) a) Customize the Imakefile to suit your system setup. On most systems this should work OK as it is. b) Make the Makefile by typing xmkmf If your system does not support generating makefiles from Imakefiles use "Makefile.std" as a template to build your own. c) If your X headers do not define APP_DEFAULTS_DIR and your default X Resource file is not /usr/X11R6/lib/X11/app-defaults/ edit bugsx.h and modify the definition for APP_DEFAULTS_DIR. On most systems things should be OK the way they are, but this gives you the possibility to customize this. d) Once you have a valid Makefile (see step a&b) build bugsx by typing make Once you have created the executable, you're ready to go. The executable will be created in the directory in which the source for bugsx resides. 10) Brief users guide You can get a list of supported options by typing one of the following: bugsx -? bugsx -help bugsx help Once you start bugsx, you get the main window containing the menu options at the top and the evenly distributed drawing windows below the 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 Interesting/useful sample settings: bugsx -interval 3 -number 4 -batch -nobreed -segments 500 bugsx -interval 3 -batch -showbreed bugsx -seed 10 10) Command line parameters bugsx accepts the following parameters as command line options: +rv reverse video (use to override xrdb entry) +synchronous syncronous mode (use to override xrdb entry) -? help -background <arg> backgound color -batch run program in batch mode -bg <arg> same as -background -bordercolor <arg> border color -borderwidth <arg> border width -cycle <arg> re-initialize population after n batch turns -display display -extend_print show extended reproduction info while running -fg <arg> same as -forground -font <arg> font -foreground <arg> forground color (also file system bar color) -geometry <arg> geometry -help help -iconic iconic -interval <arg> interval used per turn -mb show menu border -name <arg> run bugsx under this name -nobreed do not breed when running in batch mode -number <arg> number of biomorphs to draw (must be a square #) -printpop print the population when breeding -rv reverse video -seed <arg> use this seed for random number generator -segments <arg> use this many segments to draw an organism -showbreed show breeding subpopulation when in batch mode -showgenes show a graphic representation of the genes -synchronous synchronous mode -v verbose -xrm make no entry in resrouce database help help 11) XResources bugsx recognizes the following XResources. Usually bugsx will search for resources under the program name but you can override this with the -name flag. If you do not wish to use a specific application defaults file, you can execute xrdb -merge to merge your resource specifications into the XResource database. bugsx first checks in the directory pointed at by the environment variable XAPPLRESDIR. If this doesn't yield any resource definitions it checks the APP_DEFAULTS_DIR. This is defined in your headers or in bugsx.h. If you want to change this you'll have to recompile bugsx. background universal backgound color batch run program in batch mode batchbreed do not breed when running in bactch mode borderColor border color borderWidth border width cycle re-initialize population after n batch turns display display extend_print show extended reproduction info while running font font foreground universal foreground color help show help mainWin.geometry main window geometry iconic start program in iconic mode interval interval used per turn minimize minimize window size menuborder draw menu borders name run bugsxunder this name number number of biomorphs to draw (must be a square #) printpop print the population when breeding reverseVideo reverse video seed use this seed for random number generator segments use this many segments to draw an organism showbreed show breeding subpopulation when in batch mode showgenes show a graphic representation of the genes synchronous syncronous mode verbose verbose mode 12) Troubleshooting Problem: Compile failes with a problem with the catlist() function definition. Solution: In terms of portability this is the most fragile part of bugsx. I've done my best to make this portable, but there may be systems whose compiler simply throws up once he sees catlist. If you do have problems with catlist(), there are a number of things you can try: 1) Try using another compiler (gcc generally accepts the catlist() function as-is). 2) Undef/Define __STDC__ in your compiler directives. Most compilers do this via the -U flag. If these fail, you'll have to adapt catlist() for your machine. In that case, accept my apologies for the problems and please send me a mail telling me what you did so that I can integrate your fix into the sources, sparing others of this misery. Problem: Bugsx won't find my resource definitions. Solution: Bugsx handles resources as follows: a) bugsx checks in the directory pointed at by the environment variable XAPPLRESDIR. If this doesn't yield any resource definitions we go to step b. If bugsx ignores your personal resrource definitions, make sure you have XAPPLRESDIR set to the proper value and exorted. b) bugsx checks the APP_DEFAULTS_DIR. This is defined in your headers or in bugsx.h. If you want to change this you'll have to recompile bugsx. The reasoning behind this approach is to allow user preferences to take preference over the system preferences. Problem: Bugsx seems to start OK but I don't get the window. Solution: Check if your DISPLAY variable is set correctly (you can always use the -v falg to see if it does start up correctly). 13) I've found a bug. What now? Read section 11 (Troubeshooting) to see if it falls under one of the problems listed there. If not either fix it yourself or mail me. If my time allows it, I'll try to fix things. 14) I've come up with a feature which I think would be useful. Here again you can do 2 things: 1) Implement it yourself. If you do this then reread section 5 (What if you change the program?) to get an idea what I would like you to do with the result. 2) Mail me. I'll consider it and if I agree with you will implement it whenever I find time. 15) I would like to receive future releases of bugsx. Send me mail telling me that. Somewhere in the mail *list* the email address you want to receive future releases at. 16) I'm extatic about this wonderful program. How can I make the author happy? If you really feel this way, how about a short mail message telling me that you are happy about using bugsx. If you're really, really extatic, send me a postcard to this address: Steneveld 26 6715 HB Ede Holland 17) I hate this worthless program. It ruins my day. Don't use it. Don't mail me! 18) Credits Much (maybe even most) of this program is based on the program BUGS, written by Joshua R. Smith sometime 1990. I've rewritten the code to run under XWindows, fixed some minor things and added some options (both user interface wise as well as in the breeding/mutation possiblities) here and there to make it more fun to play with bugsx, but the basic engine is adapted from the original BUGS version. If you are interested in other BUGS ports, mail Joshua (firstname.lastname@example.org) about this or visit his web page at: http://physics.www.media.mit.edu/~jrs/biomorphs.ps
