Genetic Programming in C++ (Version 0.40) Copyright Adam P. Fraser, 1993,1994 This code is released for non-commercial use only. For comments, improvements (or even money !?) contact: Adam Fraser, Postgraduate Section, Dept of Elec & Elec Eng, Maxwell Building, University Of Salford, Salford, M5 4WT, United Kingdom.

Here then is the compile and go painless method of getting gpc++ up and evolving something. The files: function.cc, terminal.cc, gene.cc, gp.cc, gpv.cc, pop.cc, allelem.cc create.cc, compare.cc, eval.cc, exit.cc, generate.cc, cross.cc, gpmain.cc, rungps.cc, select.cc, loadsave.cc and tourn.cc must all be compiled together in the same directory. These components make up the basic kernel of gpc++, the last and most important component of which is the problem to be evolved. For this example you will find enclosed in the package a symbolic regression problem found in Koza GP I called symbreg.cc. If you are using the MS-DOS version you will find a file called gp.prj and gp.dsk (for Borland C/C++) this includes all the information for compiling and linking the system. [Also DOS users see DOS bit at the end of this document.] Windows Borland C/C++ users will also find a gp.def which defines the memory model of the system and further parameters, this must also be included. The conversion between DOS and Windows project files should be automatic. If you are using GNU C/C++ in UNIX you will find a makefile within the package with the correct modules to be called. If neither option is being used then simply include the file symbreg.cc into the above list using whatever method you choose. If on compilation this block of code you recieve any errors check all the files have been included and that the correct directories are being searched for the appropiate standard header files in the compiler. If it still will not work please mail the author who would also like to hear about successful compilation on Windows NT and PowerMACs. The second step is to alter the gp.ini file included in the package. Once gpc++ starts to run it reads in the values from this file and sets the respective variables within genetic programming system. The gp.ini file for the symbolic regression problem is called symbreg.ini, just rename this file. If for some reason this file cannot be found it can be created by running gpc++ without any gp.ini files in the directory in which you run the program. This will cause a default gp.ini to be produced, change this with a standard text editor. In the case of the symbolic regression this file should read. // gp.ini for the symbolic regression problem <--- this line is not important CreationType : 0 Evaluations : 1 MaxFitness : 1000 MaxCreation : 6 MaxCrossover : 17 ADFs : 0 Mutation : 0 While altering the values make sure that the names of the variables and their position within the gp.ini file (the colons are an important component of the system) are not altered. Again, a further explanation of this file and its attributes will be made later in the document. Once you have compiled the code above you are ready to go. Gpc++ is run from the command line with the population size, number of generations and output file needed by the system. If you wish to produce a run with a population of 100 and the number of generations equal to 50 with all the results going into gp.dat the command is: gp 100 50 gp There are two output files produced the file gp.dat contains the English version of the outputted program while gpb.dat contains the structure which the gpc++ system can understand. When choosing a file name for output files in DOS only seven letters can be used as the system adds a further 'b' to the file name. The problem you have just tried to evolve is a mathematical function which produces a graph similar (nay identical) to X**4 + X**3 + X**2 + X described in Koza's book. For more information either see the source code or see the 'and there is more...' section near the end. For the other problems in the package ( Artificial Ant and the LawnMower Problem) copy all files into the main directory and include the *.cc files instead of symbreg.cc alter the ini file to the correct values. ( AA: Evals = 600, Max Fitness = 91 ...... LP: Evals = 100, MaxFitness = *** ). -------------------- and there is more... -------------------- This is just a little document explaining how to get things going. The full documentation is a postscript file which you can get from ftp.cc.utexas.edu in /pub/genetic/programming/papers as gpc****.ps depending on your computer OS. --------------------- Adding chunks of code --------------------- This system is intended as a basic kernel to drape your ideas of how to do GP onto. As you may have noticed it is the work of one man, who is feeling his age (23) and wants a lie down. If you add a component, write a new problem or just have a feeling of goodwill towards me then please send a message and I will reply with warmth, compassion and citations. I thank you -- apf 15 June 1994 ----------------------------- Useless DOS memory allocation ----------------------------- gpc++ is memory hungry and is designed nowadays for machines which can access their memory. The DOS os is a pain for this and I did not want to reduce the portability of my code. If you try and use over ***0k of memory ( that includes the program and whatever other garbage you have ) the system will not crash but quietly complain and halt. To get over this you can; a) Use UNIX. b) Use Windows. c) Give up and use small populations. If you are not keen on any of these options you could buy the Watcom C/C++ compiler which produces the 32-bit code to counter DOS's inadequacies. If you are poor, like me, but have internet access you may wish to look at djgpp the DOS port of the GNU compiler. It can be found in the wsmr.simtel. navy.mil archive or a good mirror of this site. It isn't the most documented of systems and also doesn't have a nice front end but it does work which is always nice. Just thought you would like to know. ------------------------------------- Disclaimer (for my own piece of mind) ------------------------------------- Disclaimer: This software is distributed WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. ----------------------- ... if any one has got to here and is still reading you may be interested in knowing that I am going for a bit of a rest.. apf 94 - a man in shades _______________________________
